Conferences ================================================================= 1.1 Quantum Field Theory Under the Influence of External Conditions ------------------------------------------------------------------- Announcement on Hyperspace@AEI: http://hyperspace.aei.mpg.de/2011/03/18/quantum-field-theory-under-the-infl… Starting Sun, Sep 18, 2011 to Sat, Sep 24, 2011 Location: Benasque, Spain Additional Information: http://benasque.org/2011qfext/ QFEXT11 is a continuation of a series of workshops of the same title held at the University of Leipzig in 1989, 1992, 1995, 1998, 2001, 2007, at the University of Oklahoma in 2003, 2009, and at the University of Barcelona in 2005. Started with the intention of bringing about an East-West scientific dialog, QFEXT developed into one of the most prominent meetings in the field of the Casimir effect, vacuum energy, and related questions in several areas, ranging from quantum field theory and cosmology to atomic, subnuclear, and experimental physics. Typically mathematical questions related to spectral geometry are represented as well. These meetings have created a unique atmosphere where theoreticians, mathematicians and experimentalists are brought together for a week, where talks by colleagues that they might rarely hear otherwise often spark lively debate and result in numerous collaborations. QFEXT11 will also celebrate the 75th anniversary of the seminal paper "Consequences of the Dirac Theory of the Positron", by W. Heisenberg and H. Euler (Zeitschr. Phys. 98, 714-732, 1936), which played an important part in establishing the study of quantum fields in classical background fields. We plan to include a special session devoted to Heisenberg-Euler effective Lagrangians and their impact in modern physics. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.2 KITP program 2012: Bits, Branes, and Black Holes ---------------------------------------------------- Announcement on Hyperspace@AEI: http://hyperspace.aei.mpg.de/2011/03/14/kitp-program-bits-branes-and-black-… Starting Mon, Mar 19, 2012 to Fri, May 25, 2012 Location: Santa Barbara, CA, USA Additional Information: http://www.kitp.ucsb.edu/activities/dbdetails?acro=bitbranes12 Dear Colleagues, We are writing to announce the program Bits, Branes, Black Holes, to be held at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara, during the period March 19 – May 25, 2012, and to alert you that applications are now being accepted. We also encourage you to inform others who you think might be interested in applying. We coordinators will be assisted by advisors Joe Polchinski and Ted Jacobson. A summary and the latest information about the program can be found online at http://www.kitp.ucsb.edu/activities/dbdetails?acro=bitbranes12 . It is necessary for every prospective participant to set up an account and apply online, even if we have already corresponded with you about the program. There will also be a “wrap-up” conference associated with this program, entitled Black Holes and Information to be held from May 21 – 25, 2012. Further information will be posted online when it becomes available. (It is not necessary to be a program participant in order to attend the conference.) KITP programs differ from many conferences and workshops in that they create a situation where scientists learn from each other and actually do substantive research, often collaborating with other participants. To foster these interactions, KITP strongly encourages theorists to stay for as long as possible, with three weeks being the minimum stay for a regular participant. We understand, however, that experimentalists/observers often cannot manage long visits but can have a big impact even in a week, so we can be more flexible for them. Some level of financial support will be available, the amount depending on the needs of the participants and availability of funds. To apply, go to the aforementioned web page, and click on the Apply link. Application deadline: July 31, 2011. Late applications will be considered as budget and space permits. Due to space and financial constraints, however, we may not be able to accommodate everyone who applies. KITP provides office and computing facilities on-site at UC Santa Barbara and also provides help in finding living accommodations. Actual commitments of office space and financial support can be made only by written formal invitations from the KITP Director, David Gross, regardless of any communications you may have had with us. If you think you might like to participate, it will help us with our planning if you could apply early, including your proposed length of stay and any financial requirements. If you have any questions, please contact one of the coordinators. Sincerely yours, Vijay Balasubramanian <vijay [AT] physics.upenn.edu> Alex Maloney <maloney [AT] physics.mcgill.ca> Donald Marolf <marolf [AT] physics.ucsb.edu> Joan Simon <J.Simon [AT] ed.ac.uk> +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.3 Microphysics in Computational Relativistic Astrophysics (2nd circular) -------------------------------------------------------------------------- Announcement on Hyperspace@AEI: http://hyperspace.aei.mpg.de/2011/03/10/microphysics-in-computational-relat… Starting Mon, Jun 20, 2011 to Sat, Jun 25, 2011 Location: Waterloo, ON, Canada Additional Information: http://micra2011.org The Microphysics in Computational Relativistic Astrophysics (MICRA 2011) workshop will take place June 20-25 at the Perimeter Institute, in Waterloo, Ontario, Canada.

Abramowicz (NCAC, Poland; Göteborg University, Sweden) co-advisor: Prof. Ramesh Narayan (Harvard University, USA) co-advisor: Dr. Aleksander Sądowski (Harvard University, USA) Applications are invited for a four-year stipend to conduct work on the above mentioned doctorate thesis at the Nicolaus Copernicus Astronomical Center in Warsaw. The project goal is to develop accurate hydrodynamic and magnetohydrodynamic numerical codes to calculate physically realistic "Slim Disk" models for black hole accretion with luminosities in the Eddington range. The problem is considered to be one of the most interesting and challenging in today's high energy astrophysics. Slim disk models are applied to explain the observed properties of quasars, microquasars, and similar astronomical objects, which contain accreting black holes in their high luminosity states. By fitting the observed X-ray spectra (continuum and line) to those calculated from state-of-art slim disk models, and by fitting the observed variability Fourier spectra to the calculated model's oscillatory behaviour, one can deduce fundamental properties of the accreting system, and of the black hole itself. The student(s) will use numerical methods that have been developed by our scientific team in the last few years. The student(s) will improve and expand these methods. Initial projects include the following, which will naturally lead to other topics: * The alpha viscosity prescription at high luminosities, * The vertical structure of slim disks at high luminosities. The student(s) will collaborate not only with our colleagues at the Copernicus Centre (Włodek Kluźniak, Agata Różańska) and at Harvard and MIT (Jeff McClintock, Ron Remillard), but possibly also with our collaborators at the Jagiellonian University in Cracow, Astronomy Institute in Prague and Silesian University in Opava in the Czech Republic, Paris Observatory and Institute d'Astrophysique in France, Göteborg University and NORDITA in Sweden, Xiamen and Peking universities in China, Kyoto University in Japan, and University of California in USA. The studies will be conducted in Warsaw, but the student(s) should be prepared for one or two long stays at Harvard University (up to a few months). The candidate should have some experience in serious numerical simulations. Literature: Relativistic slim disks with vertical structure A.

The Living Reviews team. ------------------------------------ PUB.NO. lrr-2011-2 Uzan, Jean-Philippe "Varying Constants, Gravitation and Cosmology" ACCEPTED: 2011-03-23 PUBLISHED: 2011-03-29 FULL ARTICLE AT: http://www.livingreviews.org/lrr-2011-2 (incl. 6 Figures and 554 references) ABSTRACT: Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to matter. This will induce a violation of the universality of free fall. Thus, it is of utmost importance for our understanding of gravity and of the domain of validity of general relativity to test for their constancy. We detail the relations between the constants, the tests of the local position invariance and of the universality of free fall. We then review the main experimental and observational constraints that have been obtained from atomic clocks, the Oklo phenomenon, solar system observations, meteorite dating, quasar absorption spectra, stellar physics, pulsar timing, the cosmic microwave background and big bang nucleosynthesis. At each step we describe the basics of each system, its dependence with respect to the constants, the known systematic effects and the most recent constraints that have b een obtained. We then describe the main theoretical frameworks in which the low-energy constants may actually be varying and we focus on the unification mechanisms and the relations between the variation of different constants. To finish, we discuss the more speculative possibility of understanding their numerical values and the apparent fine-tuning that they confront us with.
