Twist Operator BOPE and Entanglement Entropy in 2D Interface CFT
Mianqi Wang
We address several aspects of entanglement entropy of 2D interface CFT using the replica method. Unlike the case of boundary CFT, we consider the boundary OPE (BOPE) of the Rényi…
One-point functions in 2D and 4D SUSY Janus
Andreas Karch, Ainesh Sanyal, Ryan C. Spieler +1
We calculate the one-point functions of the marginal operator dual to the space-varying dilaton in 4D and 2D holographic Janus interfaces, extending results in arXiv…
Universality of Dissipation across Holographic Interfaces
Andreas Karch, Mianqi Wang
Motivated by recent results in spin chains we study dissipation and relaxation in a two-dimensional holographic interface conformal field theory (ICFT) in which degrees of freedom…
Nonrenormalization Theorem for Interface Entropy
Andreas Karch, Hirosi Ooguri, Mianqi Wang
We derive a formula for the half-BPS interface entropy between any pair of theories on the same conformal manifold. This generalizes the diastasis formula derived…
