Berges, Yaffe

Meeting with all Participants

Mentioned topics of interest (no ordering):
fast apparent thermalization, turbulence, spectral density from lattice, viscous hydro, tests of truncated n-PI approximations, n-PI approx. for non-Abelian gauge theories, gauge/string duality applications, transport coefficients beyond leading order, preheating, stochastic quantization.

Edward Shuryak

Talk: AdS/CFT and Holographic Description for Nonequilibrium Processes

here are two papers where we studied falling
strings and their hologram (explosion which
is non-hydro type)
Toward the AdS/CFT gravity dual for High Energy Collisions: I.Falling into the AdS.
Shu Lin, Edward Shuryak hep-ph/0610168
II. The Stress tensor on the boundary.
arXiv:0711.0736

entropy generation by falling strings and many related issues are discussed in a short book by L.Susskind and J.Lindesay, An introduction to black holes,information and string theory revolution. I only was directed to it at KITP and found that it very much confirmed our equilibration scenario, in the sense that ONLY falling strings are going to generate EXACTLY the right amount of entropy

Additional comment from E.Shuryak:
(After Paul's paper showing small eta/s is preferred) Michael Lublinsky and myself wrote a paper
How much entropy is produced in strongly coupled Quark-Gluon Plasma (sQGP) by dissipative effects?
Phys.Rev.C76:021901,2007. arXiv:0704.1647
in which we argued that eta/s is effectively obtained at no-so-small momenta (relative to piT) and show that ADS/CFT quasinormal mode corresponding to sound has nearly factor 2 smaller effective eta/s in such kinematics. Thus there may be no contradiction between Paul's results and AdS/CFT viscosity. Misha L. will explain this when he comes.

comment from E.Shuryak:
what can a critical Re for relativistic Hubble-like explosion like we have at RHIC be is an interesting question. But probably we are way below it: otherwise the largest-size vortices would destroy accurate agreement between hydro and rdial/elliptic flow observed (and confirmed by Paul's first talk)

Fri, Jan 18

2:00pm

Auditorium

Gert Aarts

Lecture: Introduction to nonequilibrium 2PI effective action techniques

For an introductory overview (starting quite general), see here

Discussion: QED conductivity from n-PI resummation techniques

Tue, Jan 29

2:00pm

Auditorium

Tomislav Prokopec

Talk: Stochastic inflation and quantum backreaction

After the talk there will be an organizational meeting to plan next week's schedule

comment by Michael Strickland: I propose that next week I lead a discussion about how to use experimental observables like E&M observables to constrain the early-time non-EQ physics of the matter created during LHC heavy-ion collisions. ( See eg http://arxiv.org/abs/0709.3576 ) Any other ideas about how to help experimentalists pin down vitally needed information about QGP initial conditions would also be welcome in the discussion.
