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…

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 backr…

Quantum induced superradiance
Casey Cartwright, Umut Gürsoy, Juan F. Pedraza +1
Superradiance, the phenomenon enabling energy extraction through radiation amplification, is not universal to all black holes. We show that semi-classical backreaction can induce s…
