Revisiting non-relativistic limits
Kristan Jensen, Andreas Karch
We show that the full spurionic symmetry of Galilean-invariant field theories can be deduced when those theories are the limits of relativistic parents. Under the limit, the non-re…
Towards a Holographic Bose-Hubbard Model
Mitsutoshi Fujita, Sarah Harrison, Andreas Karch +2
We present a holographic construction of the large-N Bose-Hubbard model. The model is based on Maxwell fields coupled to charged scalar fields on the AdS2 hard wall. We realize the…
Conductivities for Hyperscaling Violating Geometries
Andreas Karch
We show that many results about holographic conductivities in geometries with hyperscaling violating scaling can be reproduced from simple scaling laws in the dual field theory. We…
Flavored N=4 SYM -- a highly entangled quantum liquid
Han-Chih Chang, Andreas Karch, Christoph F. Uhlemann
We study N=4 SYM theory coupled to fundamental N=2 hypermultiplets in a state of finite charge density. The setup can be described holographically as a configuration of D3 and D7 b…
The holographic dual of a Hawking pair has a wormhole
Kristan Jensen, Andreas Karch, Brandon Robinson
In previous work, two of us constructed the holographic dual of a single Einstein-Podolsky-Rosen (EPR) pair in maximally supersymmetric Yang-Mills theory. Here we extend that work…
Generalized gravitational entropy of probe branes: flavor entanglement holographically
Andreas Karch, Christoph F. Uhlemann
The notion of generalized gravitational entropy introduced by Lewkowycz and Maldacena allows, via the AdS/CFT correspondence, to calculate CFT entanglement entropies. We adapt the…
