    Loops '09

    First Announcement
    International Conference on Quantum Gravity: Loops '09

    The annual international conference on non-perturbative/background independent
    quantum gravity will take place from 2 to 8 August 2009 at Beijing Normal
    University in China. It stands in the tradition of Loops '04 in Marseille, Loops
    '05 in Potsdam and Loops '07 in Morelia, but is more concentrated on the issues
    and approaches closely related to loop quantum gravity. The main topics include:

    * Loop quantum gravity
    * Loop quantum cosmology and other symmetric models
    * Spin foams and their low energy ramifications
    * Fundamental questions of quantum gravity
    * Cosmology related to quantum gravity
    * Phenomenology of quantum gravity.

    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...

    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...

    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 13 Twistorial structure of loop quantum gravity transition amplitudes Simone Speziale CPT-CNRS, Marseille
    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.
