Holographic Black Hole Chemistry
Andreas Karch, Brandon Robinson
Thermodynamic quantities associated with black holes in Anti-de Sitter space obey an interesting identity when the cosmological constant is included as one of the dynamical variabl…
Spinor fields in general Newton-Cartan backgrounds
John F. Fuini, Andreas Karch, Christoph F. Uhlemann
We give a covariant construction of Lagrangians for spinor fields in generic Newton-Cartan backgrounds. A non-relativistic Dirac/Levy-Leblond operator and the associated fields are…
A Precision Test of AdS/CFT with Flavor
Andreas Karch, Brandon Robinson, Christoph F. Uhlemann
In this letter we put AdS/CFT dualities involving probe branes to a precision test. On the holographic side we use a new class of supersymmetric D7-brane embeddings into AdS$_5\tim…
Supersymmetric D3/D7 for holographic flavors on curved space
Andreas Karch, Brandon Robinson, Christoph F. Uhlemann
We derive a new class of supersymmetric D3/D7 brane configurations, which allow to holographically describe N=4 SYM coupled to massive N=2 flavor degrees of freedom on spaces of co…
Multiband models for field theories with anomalous current dimension
Andreas Karch
We give simple examples of weakly coupled or free quantum mechanical systems that exhibit scale invariance with an anomalous dimension for a conserved current. In these models scal…
