Re: Announcements

The second post above was ruled out 1 week after its "detection" at ~3 sigma. This is about the same precision of the sign above, and it is only 1 sign at 150 GeV. The number 5 comes due to that the theory to which the search parameters were fixed yield 5 higgs...

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.
Week 4: Several combinations of topics covered in the previous weeks are possible to arrive at concluding statements. (Details of this week will be scheduled short notice, capturing those topics that have emerged as the most important ones.)
==endquote==
Chairs: Hossenfelder, Giesel, Sakellariadou, Bojowald
Other participants folks here might recognize: Lewandowski, Kiefer, Thiemann, Calcagni, Brandenberger, Ambjorn, Loll, Mavromatos, Sotiriou, Nelson, Steinhacker, Campiglia...

A potentially interesting conference this month at Perimeter:

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 [Broken]
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 [Broken]
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.

Nov. 27 Coarse graining: towards a cylindrically consistent dynamics Bianca Dittrich Perimeter Institute

http://relativity.phys.lsu.edu/ilqgs/ (online audio and slides PDF)

The topic of Dittrich's talk (coarse graining) relates to a paper she co-authored earlier this year:
http://arxiv.org/abs/1208.3388
Holonomy Spin Foam Models: Definition and Coarse Graining
Incidental information: Dittrich is one three Perimeter faculty on the committee organizing next year's Loops conference at PI, and also the senior person in charge of organizing LQG parallel sessions at the GR-20 conference to be held next year in Warsaw.

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 :smile:) 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
===quote==

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.
The abstracts for the Loops 2013 parallel sessions are listed alphabetically by speaker:

Dec 10 TBA	                                     Saeed Rastgoo	 Morelia
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.
