sQGP as hCFT
Alex Buchel, Michal P. Heller, Robert C. Myers
We examine the proposal to make quantitative comparisons between the strongly coupled quark-gluon plasma and holographic descriptions of conformal field theory. In this note, we ca…
Cuscuton and low energy limit of Horava-Lifshitz gravity
Niayesh Afshordi
A proposal for a power-counting renormalizable theory of quantum gravity at a Lifshitz point was recently put forth by Horava (arXiv:0901.3775), and has been since dubbed as Horava…
Loop operators and S-duality from curves on Riemann surfaces
Nadav Drukker, David R. Morrison, Takuya Okuda
We study Wilson-'t Hooft loop operators in a class of N=2 superconformal field theories recently introduced by Gaiotto. In the case that the gauge group is a product of SU(2) group…
Non-relativistic metrics with extremal limits
Emiliano Imeroni, Aninda Sinha
We present solutions of type IIB supergravity with z=2 Schrodinger asymptotics that admit an extremal limit, i.e. the black hole horizon has a double zero. These solutions are obta…
Self-dual Black Holes in LQG: Theory and Phenomenology
Leonardo Modesto, Isabeau Prémont-Schwarz
In this paper we have recalled the semiclassical metric obtained from a classical analysis of the loop quantum black hole (LQBH). We show that the regular Reissner-Nordstrom-like m…
Group field theory renormalization - the 3d case: power counting of divergences
Laurent Freidel, Razvan Gurau, Daniele Oriti
We take the first steps in a systematic study of Group Field Theory renormalization, focusing on the Boulatov model for 3D quantum gravity. We define an algorithm for constructing…
