Non-relativistic holography from Horava gravity
Stefan Janiszewski, Andreas Karch
Many non-relativistic Quantum Field Theories with conserved particle number share a common set of symmetries: time dependent spatial diffeomorphisms acting on the background metric…
String theory embeddings of non-relativistic field theories and their holographic Horava gravity duals
Stefan Janiszewski, Andreas Karch
We argue that generic non-relativistic quantum field theories have a holographic description in terms of Horava gravity. We construct explicit examples of this duality embedded in…
Novel Solutions of Finite-Density D3/D5 Probe Brane System and Their Implications for Stability
Han-Chih Chang, Andreas Karch
In this article we present a novel set of solutions of the probe brane system consisting of Nf-D5 probe branes embedded in the near-horizon geometry generated by Nc-D3 branes, with…
Hyperscaling-Violation on Probe D-Branes
Martin Ammon, Matthias Kaminski, Andreas Karch
For the field theories dual to D3/D7- and D3/D5-brane systems we find non-relativistic finite density fixed points exhibiting a violation of hyperscaling. This violation is measure…
SL(2,Z) Action on AdS/BCFT and Hall Conductivities
Mitsutoshi Fujita, Matthias Kaminski, Andreas Karch
We study the response of a conserved current to external electromagnetic fields in a holographic system with boundaries using the recently proposed AdS/BCFT (boundary conformal fie…
Holographic realization of large-Nc orbifold equivalence with non-zero chemical potential
Masanori Hanada, Carlos Hoyos, Andreas Karch +1
Recently, it has been suggested that large-Nc orbifold equivalences may be applicable to certain theories with chemical potentials, including QCD, in certain portions of their phas…
