Radius Destabilization in Five Dimensional Orbifolds from Lorentz Violating Fields
Authors: https://www.physicsforums.com/member.php?u=7733"
Abstract: One of the challenges in connecting higher dimensional theories to cosmology is stabilization of the moduli fields. We investigate the role of a Lorentz violating vector field in the context of stabilization. Specifically, we compute the one loop Casimir energy in Randall-Sundrum 5-dimensional (non-supersymmetric) S^1/ Z_2 orbifolds resulting from the interaction of a real scalar field with periodic boundary conditions with a Lorentz violating vector field. We find that the result is an enhanced attractive Casimir force. Hence, for stability, positive contributions to the Casimir force from branes and additional fields would be required to counter the destabilizing, attractive effect of Lorentz violating fields.


Regards, Hans

Oporto meeting on Approaches to Quantum Gravity--what can we learn?

http://faraday.fc.up.pt/omgtp2008/
Every year there is the Oporto Meeting on Geometry Topology and Physics. This year the theme of the Oporto Meeting will be Approaches to Quantum Gravity.

There will be four main speakers. We can see the titles of their talks and find (more or less) corresponding papers that they have already posted on arxiv. So we can easily find current research papers which Oporto, in effect, puts the spotlight on. Let's see what we can learn by studying the program of four main talks.

Recall that QG is not a fixed academic subject but is dynamically changing. How experts and active researchers in the field see it can change considerably over the course of a few years, or even from year to year.

MAIN SPEAKERS
The main speakers will each give a minicourse of three one-hour lectures.

Ali CHAMSEDDINE (American U. of Beirut & IHES, Bures-sur-Yvette)
Classification of discrete noncommutative geometries and the uniqueness of the standard model

Steven GIDDINGS (University of California, Santa Barbara)
Probing nonperturbative gravity: black holes, locality, and cosmology

Renate LOLL (Utrecht University)
Quantum Gravity from Causal Dynamical Triangulations

Thomas THIEMANN (Max Planck Institute for Gravitational Physics, Golm)
Loop Quantum Gravity

 

[marcus]

Ali Chamseddine, Classification of discrete noncommutative geometries and the uniqueness of the standard model

Abstract:

Assuming that space-time is a product of a continuous four-dimensional manifold times a discrete space F, we classify the irreducible geometries F consistent with imposing reality and chiral conditions on spinors. Remarkably we find that the noncommutative geometry of the standard model results almost uniquely, with all the necessary details. In particular we prove that the number of fermions per generation is 16, the square of an even integer. The spectral action of this geometry is constructed, and the model is analyzed.
==================================

Steven Giddings, Probing nonperturbative gravity: black holes, locality, and cosmology

Abstract:

I will describe conflict of general physical principles in the non-perturbative regime of quantum gravity, particularly involving black holes. Notably, this conflict suggests reexamination of the principle of locality. If there is time, some related aspects of cosmology will be discussed.
====================================

Renate Loll, Quantum Gravity from Causal Dynamical Triangulations

Abstract:

I discuss motivation, implementation and results of the nonperturbative approach to quantum gravity based on Causal Dynamical Triangulations, including the recent reconstruction of de Sitter space from quantum fluctuations.
======================================

Thomas Thiemann, Loop Quantum Gravity

Abstract:

We give an introduction to the main concepts of Loop Quantum Gravity
===============endquote=======================

These are the abstracts. Each of the four main speakers will give a three-hour mini-course on these topics spread out over the several days of the conference (10-13 July). Let's see what papers we can find that tie in here and what we can learn from them.

 

[marcus]

Giddings is the String thinker in the lineup. Here is the recent paper of his that matches the topic:
http://arxiv.org/abs/0705.2197
Black holes, information, and locality
Steven B. Giddings
(last revised 5 Feb 2008)

"Thirty years of a deepening information paradox suggest the need to revise our basic physical framework. Multiple indicators point toward reassessment of the principle of locality: lack of a precise definition in quantum gravity, behavior of high-energy scattering, hints from strings and AdS/CFT, conundrums of quantum cosmology, and finally lack of good alternative resolutions of the paradox. A plausible conjecture states that the non-perturbative dynamics of gravity is unitary but nonlocal. String theory may directly address these issues but so far important aspects remain elusive. If this viewpoint is correct, critical questions are to understand the 'correspondence' limit where nonlocal physics reduces to local quantum field theory, and beyond, to unveil principles of an underlying nonlocal theory."
=============================

Loll mentioned that when they integrate what is essentially a Feynman path integral thru the space of geometries, they get de Sitter space. That is, a maximally symmetric spacetime with positive cosmological constant. This corresponds to a recent paper:

http://arxiv.org/abs/0712.2485
Planckian Birth of the Quantum de Sitter Universe
Authors: J. Ambjorn, A. Gorlich, J. Jurkiewicz, R. Loll
4 pages, 3 figures
(Submitted on 17 Dec 2007)

"We show that the quantum universe emerging from a nonperturbative, Lorentzian sum-over-geometries can be described with high accuracy by a four-dimensional de Sitter spacetime. By a scaling analysis involving Newton's constant, we establish that the linear size of the quantum universes under study is in between 17 and 28 Planck lengths. Somewhat surprisingly, the measured quantum fluctuations around the de Sitter universe in this regime are to good approximation still describable semiclassically. The numerical evidence presented comes from a regularization of quantum gravity in terms of causal dynamical triangulations."
==========================

I think I will discuss some of the physics in THIS paper, as a sample of what will be highlighted at Oporto this summer. That seems like one way to learn something from the Oporto Meeting's program, or to let it teach us something. If anyone else wants to discuss some of the other content, that's fine too.

Strings '08 speaker list

Strings '08 will be at CERN August 18-23
The speaker list is here:
http://ph-dep-th.web.cern.ch/ph-dep-th/content2/workshops/strings2008/?site=content/talks.html
All the talks are plenary session and all speakers are invited (there are no parallel sessions with volunteered talks).
There are 8 one-hour summary overview talks listed and about 30 half-hour research talks. It is an unusually compact format, for what is usually a large well-attended conference.
Here is what the welcome page at the webite has to say:
"Welcome to Strings 2008, which will be held at CERN in the year during which the LHC starts up. ... For more details about the conference, see the links on the left.

The lectures will take place in the CERN main auditorium. All participants must register in order to get admitted to the lecture hall. There will be about 40 talks, most of which are summaries of 30 minutes each, but each day there will also be one or two more comprehensive, one hour review talks. The speakers will be nominated by the committee, and self-applications are discouraged. The precise schedule will be announced on this website shortly before the meeting. "

Congratulations Francesca!

PF member Francesca is in Rovelli's group at Marseille. The homogeneity assumption needs to be relaxed in LQC, to bring LQC closer to the full LQG theory. They found a way to do it partway in a gradual fashion. Recently Rovelli delivered an online seminar talk about this at ILQGS.

QG school and workshop at Sussex in September

The main event is a 3-day workshop 17-19 September 2008
http://www.ippp.dur.ac.uk/Workshops/08/CLAQG
This will be held at Sussex and admission is free. It will be preceded by a 2-day school
15-16 September aimed at getting graduate students and postdocs entering the field prepared with the basics so they can get maximum benefit from the workshop.
http://www.ippp.dur.ac.uk/Workshops/08/NPMQFT

The workshop is called
Workshop on Continuum and Lattice Approaches to Quantum Gravity (CLAQG)
and the main speakers will be

* Jan Ambjorn (NBI Copenhagen)
* Damiano Anselmi (U Pisa)
* Emil Bjerrum-Bohr (IAS Princeton)
* Daniel Litim (U Sussex)
* Renate Loll (U Utrecht)
* Max Niedermaier (U Tours)
* Roberto Percacci (SISSA Trieste)
* Martin Reuter (U Mainz)
* Thomas Thiemann (AEI Golm and Perimeter Institute)

It is noteworthy that TRIANGULATIONS or lattice QG and also ASYMPTOTIC SAFETY QG are each represented by several speakers. Jan Ambjorn and Renate Loll are both speaking about the triangulations work. Roberto Percacci, Max Niedermaier, and Martin Reuter, pursuing the asymptotic safety approach, are there as well.

In both these two approaches they find that the quantum spacetime continuum does not have a fixed dimensionality, but that a 4D smooth continuum emerges at larger scale while at smaller (trans-Planck) scale the dimension goes down and the spacetime is rougher.

The two approaches are in a sense natural allies because they confirm each other. They find similar mathematical reality coming from different directions. This mutual support has been made explicit in numerous papers and at last years Loops 07 conference.

It looks to me as if this Sussex school and workshop is in effect recruiting brainpower into the field. There is a lot of work to be done in this field and they can use a lot of grad students and postdocs.

The two-day preparatory school before the workshop is called
School on Non-Perturbative Methods in Quantum Field Theory (NPMQFT)

* Basics of the non-perturbative renormalisation group (D. Litim, U Sussex)
* Basics of the RG for QCD and confinement (J.M. Pawlowski, U Heidelberg)
* Basics of QCD on the lattice (O. Philipsen, U Muenster)
* Basics of asymptotic safety for gravity (M. Niedermaier, U Tours)
* Basics of the RG for quantum gravity (M. Reuter, U Mainz)
* Basics of lattice quantum gravity I (R. Loll, U Utrecht)
* Basics of lattice quantum gravity II (J. Barrett, U Nottingham) (t.b.c.)

School starts 9AM Monday morning 15 September and Workshop ends 6PM Friday evening 19 September.
Notice that the participation of John Barrett is "to be confirmed".
Notice that Renate Loll is calling the causal dynamical triangulations (CDT) approach by the name "lattice quantum gravity".
This has the acronym LQG causing a mildly stimulating subliminal shock. In a nonperturbative lattice approach to spacetime geometry, the lattice is not a fixed regular lattice, but is, in effect, a random dynamical triangulation. Evidently one can call triangulation QG by the name lattice QG but making clear that it is a nonperturbative and background independent approach.
Anyway that is the list of topics to be covered in the school

 

[marcus]

The first week of September there will be something called
INTERNATIONAL SCHOOL OF SUBNUCLEAR PHYSICS
46th Course: Predicted and Totally Unexpected in the Energy Frontier Opened by LHC
Directors: G. 't HOOFT – A. ZICHICHI
29 August – 7 September 2008

and the interesting thing---why I mention it, and ask if anyone has more information---is the quantum gravity angle. Apparently Renate Loll is lecturing at the school.
Loll does simplicial quantum geometry. Her group at Utrecht is on a roll and has remarkable new results---the emergence of a smooth de Sitter universe from chaotic quantum ground, for example, estimates the size of quantum fluctuations in geometry at various scales.

So how does that fit in with the theme of "Totally Unexpected at the LHC Frontier"?

Here's a link
http://www.ccsem.infn.it/
Here's Loll's page mentioning the School of Subnuclear Physics in September at Erice, Sicily
http://www.phys.uu.nl/~loll/Web/seminars/seminars.html

Wow! I just saw the poster for the school. It is worth downloading. You can get it from the ccsem link I just gave by clicking on posters and selecting the Subnuclear Physics one.
The poster has a list of lectures on hot theory topics.
't Hooft on Crystalline Gravity
Lee Smolin on Loop Quantum Gravity
John Schwarz on Superstring/M
Renate Loll on Dynamical Triangulations Gravity
S. Ferrara on SUSY
Z. Bern on SUGRA

It is pretty select blue chip company. Leonard Susskind was invited but not to lecture (they already have Superstring represented by John Schwarz). The line-up gives an up-to-date perspective on what the organizers consider hot theory topics as we approach LHC startup.

Besides the theory lectures, they have talks by experimentalists on projected signals at LHC. It looks like it'll be a grand school! Maybe some people we know will be able to attend. Part of the stated aim of the Erice school is to encourage and inspire young physicists so they appear to have places and support for a substantial number. We'll see.

John's nice exposion o Loll's gravity on his blog!

http://golem.ph.utexas.edu/category/2008/07/causality_in_discrete_models_o.htm

The initial post is given by a guest, Gavin Wraith. Later John posts some information about it and gives some of his ideas about that approach.

For example, he also tries to link Loll's gravity with spin foams.

http://math.ucr.edu/home/baez/loops05/loops05.pdf

He is also asking question and more ideas there.

I think Marcus must go there do something.

From the thread "String Field Theory and Background Independence?"

But may it's true that "all roads lead to Rome". The question is just which roads are the fastest, through the string bush, or some other way.

A potentially interesting conference next month in Stockholm:
Perspectives of Fundamental Cosmology
google "fundamental cosmology stockholm" to get the website.
http://agenda.albanova.se/conferenceDisplay.py?confId=2998
==quote==
Week 1: Fundamental theories of space-time. Here, the main approaches will be introduced by some of the experts in the fields, with a focus on the resulting models for early-universe cosmology.
Week 2: Cosmological and high-energy phenomenology. The various implications of fundamental theories for cosmology and high-energy physics will be discussed.
Week 3: Cosmology and high-energy physics. In this week, a general discussion of the potential of cosmological and high-energy observations will be carried out.

A potentially interesting conference this month at Perimeter:
Experimental Search for Quantum Gravity
http://www.perimeterinstitute.ca/en/Events/Experimental_Search_for_QG/Experimental_Search_for_Quantum_Gravity%3A_the_hard_facts/

The schedule of talks day by day:

Abstracts of about 40 of the talks (several seem quite interesting):

About 60 participants listed--nice mix of AsymSafeQG, LoopQG, observatory and lab QG Pheno, other:

It surprised me to see how much lab work they plan to discuss: new kinds of clocks and other instruments applicable to QG.

2013 Zakopane School (June 28 - July 7)

This will be a QG+related school. It will take place in the Polish mountain resort (where several LQG schools and workshops have been held in recent years) and it will precede a major triennial conference on General Relativity and Gravitation (GR-20) which will this time be held in Warsaw.

So the Zakopane school is one way that QG grad students and young researchers can warm up for the GR-20 and the Loops 2013 conferences planned for July.

http://th-www.if.uj.edu.pl/school/2013/speakers&titles.html
This time the school has a broader range of topics and is funded by Polish institutions instead of the ESF (the EU science foundation) which sponsored the earlier Zakopane QG schools and workshops. But as you can see there is some overlap:

Jan AMBJORN (NBI Copenhagen) TBA
Abhay ASHTEKAR* (PennState) Quantum Gravity and Cosmology
Eugenio BIANCHI (Perimeter Inst.) TBA
Renate LOLL (Utrecht Univ.) Simplicial Gravity
Ilya MANDEL (Birmingham Univ.) LIGO Experiment
Viatcheslav MUKHANOV (Munchen Univ.) TBA
Hans RINGSTROM (KTH Stockholm) Cauchy Problem in General Relativity
Ulrich SPERHAKE (CALTECH) TBA
Thomas THIEMANN (FAU Erlangen) TBA
David TONG (Cambridge) AdS/CMT
Robert M. WALD (Chicago Univ.) Thermodynamics and Stability of Black Holes
Toby WISEMAN (Imperial College) Ads/CMT
N.N. (VIRGO) VIRGO Experiment

Here are links for the large triennial conferences taking place later that month.
GR-20 Warsaw (week of 7 July):
http://gr20-amaldi10.edu.pl/index.php?id=18
Loops 2013 Perimeter Institute (week of 21 July):
http://www.perimeterinstitute.ca/conferences/loops-13

Jerzy Lewandowski, the main organizer of the Warsaw GR-20 conference, writes this about the Zako school:
==quote==
before GR20/Amaldi10 there will be a school
on:
loop quantum gravity, simplicial gravity,
mathematical and numerical gravity,
topics in classical gravity + experiment,
conformal symmetry in condensed matter physics,
conformal fielfd theory and AdS/CFT correspondence.
==endquote==
So we can see that there is a nice range of interrelated topics for which he and others have been getting speakers.

Do we need a physics of PASSAGE?
http://prce.hu/centre_for_time/jtf/FullProgram.pdf
The "block universe" idea (with time as a pseudo-spatial "dimension") is under pressure, and it may (in time ) be modified, reformed, or replaced.
This month there is a conference in Capetown South Africa bringing together Philosophers Physicists Linguistics folks and others to discuss the current state of this challenge to the spacetime block.

The local host George Ellis co-authored "Large Scale Structure of Space-Time" with Stephen Hawking. Ellis now has his own challenge to the conventional block universe. The basic problem is that the conventional block is incompatible with quantum theory.

The physicists are an interesting bunch (note the Causal Sets people):
Carlo Rovelli
George Ellis
Rafael Sorkin
Faye Dowker
Dan Oriti
Edward Anderson

Do We Need a Physics of ‘Passage’?
10 — 14 December, 2012 :: Vineyard Hotel & Spa, Capetown, South Africa
Philosophers: David Albert, Christophe Bouton, David Braddon-Mitchell, Jeremy Butterfield, Christoph Hoerl, *Luciano Floridi, Rick Grush, Nick Huggett, Kristie Miller, Wayne Myrvold, Huw Price, Dean Rickles, Don Ross, Jos Uffink.
Physicists: Edward Anderson, Fay Dowker, Avshalom Elitzur, George Ellis, Daniele Oriti, Carlo Rovelli, Rafael Sorkin.
Psychologists & linguists: Alex Holcombe, Teresa McCormack, Kia Nobre, Chris Sinha.
...
...Twentieth century physics is often thought to have established that there is no distinction between past, present and future, no flow of time, and no fundamental direction of time. This viewpoint — the Block Universe, as it is sometimes called — is reflected in remarks such as the following:
We physicists know that the distinction between past, present and future is only a stubbornly persistent illusion. (Einstein)

The objective world simply is, it does not happen. Only to the gaze of my consciousness, crawling upward along the world-line of my body, does a section of the world come to life as a fleeting image in space which continuously changes in time. (Weyl)

...
However, the Block Universe view is under challenge from within physics, from theorists such as George Ellis, Lee Smolin and Chris Fuchs, who believe that in leaving out these elements, physics is missing something essential.

Thus there is a disagreement within physics about the proper aims of physics, in the case of the study of time. We believe that this is a clear case in which in order the resolve the disagreement within physics, we need to step back from physics and consider the question of 'what belongs where' in the study of time from a broader interdisciplinary perspective—informed, among other things, by expertise from the psychology of temporal perception and from the metaphysics of time.

An April 2013 conference presenting analysis of the initial results from the Planck mission of the European Space Agency
http://congrexprojects.com/13a11
(Thanks to Skydive Phil for spotting this)
By mapping the CMB background of ancient light, in higher resolution than was possible with the WMAP mission, Planck may help constrain quantum gravity/cosmology models of the start of expansion--bounce models in particular--and inflation.

For the most part these are 20 minute talks, in sets of 4 or 5 on one recording. The numbers in parentheses give the approximate minute on the recording when the talk starts.
When you go to the pirsa recording, if the talk you want is not the first one of the set, you may need to allow time for BUFFERING: start the play, mute the sound, and do something else for a few minutes. Buffering time is roughly 10X faster than real time.

I notice 3 talks from the Morelia campus of UNAM, which is where Robert Oeckl is based (General Boundary Formulation of QFT). The 3 September talk is about GBF, it might be useful to review Oeckl's talk about GBF that is linked in the preceding post #49. The General Boundary formalism seems to be the natural way to do both transition amplitudes and statistical mechanics in a general covariant way. That is, with the focus being on processes, with no preferred time, rather than on a system's state at some designated time.

In connection with the list of parallel session talks in post #49, I note that ATOUSA SHIRAZI who gave a very interesting talk on her work at Florida Atlantic with Jon Engle was mistakenly alphabetized in the C bunch rather than the S bunch.
