Holographic Lattices, Dimers, and Glasses
Shamit Kachru, Andreas Karch, Sho Yaida
We holographically engineer a periodic lattice of localized fermionic impurities within a plasma medium by putting an array of probe D5-branes in the background produced by N D3-br…
Notes on Properties of Holographic Matter
Andreas Karch, Manuela Kulaxizi, Andrei Parnachev
Probe branes with finite worldvolume electric flux in the background created by a stack of Dp branes describe holographically strongly interacting fundamental matter at finite dens…
ABJM Mirrors and a Duality of Dualities
Kristan Jensen, Andreas Karch
We clarify how mirror symmetry acts on 3d theories with N=2,3 or 4 supersymmetries and non-abelian Chern-Simons terms and then construct many new examples. We identify a new dualit…
Electric-Magnetic Duality and Topological Insulators
Andreas Karch
We work out the action of the SL(2,Z) electric-magnetic duality group for an insulator with a non-trivial permittivity, permeability and theta-angle. This theory has recently been…
Critical Exponents from AdS/CFT with Flavor
Andreas Karch, Andy O'Bannon, Laurence G. Yaffe
We use the AdS/CFT correspondence to study the thermodynamics of massive N=2 supersymmetric hypermultiplet flavor fields coupled to N=4 supersymmetric SU(Nc) Yang-Mills theory, for…
Alternative large Nc baryons and holography
Carlos Hoyos-Badajoz, Andreas Karch
In gauge theories in the limit of a large number Nc of colors, baryons are usually described as heavy solitonic objects with mass of order Nc. We discuss an alternative large Nc de…
A holographic perspective on non-relativistic conformal defects
Andreas Karch, Piotr Surowka, Ethan G. Thompson
We study defects in non-relativistic conformal field theories. As in the well-studied case of relativistic conformal defects, we find that a useful tool to organize correlation fun…
From gauge-string duality to strong interactions: a Pedestrian's Guide
Steven S. Gubser, Andreas Karch
We survey recent progress in understanding the relation of string theory to quantum chromodynamics, focusing on holographic models of gauge theories similar to QCD and applications…
