Bubbling wormholes and matrix models
Panos Betzios, Ji Hoon Lee, Olga Papadoulaki +1
The thermofield double state entangles two copies of a CFT via a sum over energy eigenstates and is dual to the two-sided eternal black hole. We explore an analogous construction u…

Near-extremal quantum cross-section for charged fields and superradiance
Panos Betzios, Olga Papadoulaki, Yanjun Zhou
We study the scattering and absorption properties of charged scalar fields on a near-extremal Reissner-Nordström black hole background. We show that in this low-temperature regime…

An Interacting, Higher Derivative, Boundary Conformal Field Theory
Christopher P. Herzog, Yanjun Zhou
We consider a higher derivative scalar field theory in the presence of a boundary and a classically marginal interaction. We first investigate the free limit where the scalar obeys…
