symmetric gravity and finite coupling holography
Umut Gürsoy, Pedro Vicente Marto, Edwan Préau
We construct asymptotically AdS black brane solutions in a theory of gravity with an infinite series of curvature corrections. The action is based on an symmetric ansa…
Perturbing a quantum black hole
Casey Cartwright, Umut Gürsoy, Juan F. Pedraza +1
We analyze the analytic structure of correlators in the field theory dual to the quantum Bañados-Teitelboim-Zanelli (qBTZ) black hole, a braneworld model incorporating exact backre…
A supersymmetric spin current
Casey Cartwright, Domingo Gallegos, Umut Gürsoy +2
We study the supersymmetric structure of the spin current in four dimensional supersymmetric theories. By coupling the stress tensor multiplet to a vierbein multipl…
Holographic transport in anisotropic plasmas
Tuna Demircik, Domingo Gallegos, Umut Gürsoy +2
We study energy-momentum and charge transport in strongly interacting holographic quantum field theories in an anisotropic thermal state by contrasting three different holographic…
Universal rapidity scaling of entanglement entropy inside hadrons from conformal invariance
Umut Gürsoy, Dmitri E. Kharzeev, Juan F. Pedraza
When a hadron is probed at high energy, a nontrivial quantum entanglement entropy inside the hadron emerges due to the lack of complete information about the hadron wave function e…
Holographic entanglement as nonlocal magnetism
Umut Gürsoy, Juan F. Pedraza, Guim Planella Planas
The Ryu-Takayanagi prescription can be cast in terms of a set of microscopic threads that help visualize holographic entanglement in terms of distillation of EPR pairs. While this…
