2d affine XY-spin model/ 4d gauge theory duality and deconfinement

Mohamed M. Anber, Erich Poppitz, Mithat Unsal

We introduce a duality between two-dimensional XY-spin models with symmetry-breaking perturbations and certain four-dimensional SU(2)and SU(2)/Z_2 gauge theories, compactified on a…

Unitarity and the Holographic S-Matrix

A. Liam Fitzpatrick, Jared Kaplan

The bulk S-Matrix can be given a non-perturbative definition in terms of the flat space limit of AdS/CFT. We show that the unitarity of the S-Matrix, ie the optical theorem, can be…

Creation of Matter in the Universe and Groups of Type E7

Sergio Ferrara, Renata Kallosh

We relate the mechanism of matter creation in the universe after inflation to a simple and universal mathematical property of extended N > 1 supergravities and related compactifica…

Cosmic Clustering

Dionysios Anninos, Frederik Denef

We show that the late time Hartle-Hawking wave function for a free massless scalar in a fixed de Sitter background encodes a sharp ultrametric structure for the standard Euclidean…

Fractionalization of holographic Fermi surfaces

Sean A. Hartnoll, Liza Huijse

Zero temperature states of matter are holographically described by a spacetime with an asymptotic electric flux. This flux can be sourced either by explicit charged matter fields i…

Universality of the Volume Bound in Slow-Roll Eternal Inflation

Sergei Dubovsky, Leonardo Senatore, Giovanni Villadoro

It has recently been shown that in single field slow-roll inflation the total volume cannot grow by a factor larger than e^(S_dS/2) without becoming infinite. The bound is saturate…
