\n"The chiral magnetic effect and chiral hydrodynamics of relativist ic plasmas"

\n\n The interplay of quantum anomalies\, topology and magnetic field\nresults in a number of surprising phenomena in relativist ic plasmas. In particular\, the\nchirality imbalance induces the separatio n of electric charge along the axis of magnetic\nfield (the Chiral Magneti c Effect\, CME). The existence of CME has been\nconfirmed by the lattice Q CDxQED computations\, and there is an\nevidence for it from heavy ion expe riments at RHIC and LHC. The CME\ncurrent is non-dissipative\, and persist s in strongly coupled systems\nthat admit hydrodynamical description. Quan tum anomalies significantly\naffect the hydrodynamics of relativistic plas mas leading in particular\nto the emergence of novel gapless collective ex citations. Apart from\nthe quark-gluon plasma\, the CME current and relate d phenomena can\nexist in chiral materials (e.g. graphene\, topological in sulators\, and\nWeyl semi-metals).

\n** 11 a.m.-12 p.m. - Mirjam
Cvetic (University of Pennsylvania) \n"General Black Holes and Their
Microscopics"**

\n\nWe review properties of multi-charged rotating b lack holes in asymptotically Minkowski and anti-deSitter space-times\, as solutions of maximally supersymmetric compactifications of String Theory. We focus on recent progress in deriving the conformal invariance and the m icroscopics of general\, asymptotically flat rotating black holes in four- and five-dimensions.\n

\n** 2-3 p.m. - Vijay Balasubramanian (Universi
ty of Pennsylvania)\n"Momentum space entanglement and renormalization
in quantum field theory" **\nThe degrees of freedom of any interact
ing quantum field theory are entangled in momentum space. Thus\, in the va
cuum state\, the infrared degrees of freedom are described by a density ma
trix with an entanglement entropy. We derive a relation between this densi
ty matrix and a Wilsonian effective action. We argue that the entanglement
entropy of and mutual information between subsets of field theoretic degr
ees of freedom at different momentum scales are natural observables in qua
ntum field theory and demonstrate how to compute these in perturbation the
ory. The results may be understood heuristically based on the scale-depend
ence of the coupling strength and number of degrees of freedom. We measure
the rate at which entanglement between degrees of freedom declines as the
ir scales separate and suggest that this decay is related to the property
of decoupling in quantum field theory.\n

\n**3-4 p.m. - Paul Langacker
(Institute for Advanced Study) \n"New Physics from the String Vacuum"
**

\n\nConcrete semi-realistic string constructions often lead to pr edictions for low energy physics that\nare more complicated than the usual MSSM paradigm. These often include string remnants such as additional U( 1)' gauge symmetries\, extended quasi-chiral fermion sectors\, and extende d Higgs/neutralino sectors.\nNon-standard mechanisms for obtaining small D irac or Majorana neutrino masses (or both) are another common occurence. E xamples of such ``beyond the MSSM'' physics and their consequences will be discussed\, mainly drawn from Type IIA quivers.\n
