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…
