Gravity Dual of Quantum Information Metric
Masamichi Miyaji, Tokiro Numasawa, Noburo Shiba +2
We study a quantum information metric (or fidelity susceptibility) in conformal field theories with respect to a small perturbation by a primary operator. We argue that its gravity…
cMERA as Surface/State Correspondence in AdS/CFT
Masamichi Miyaji, Tokiro Numasawa, Noburo Shiba +2
We present how the surface/state correspondence, conjectured in arXiv:1503.03542, works in the setup of AdS3/CFT2 by generalizing the formulation of cMERA. The boundary states in c…
Scrambling time from local perturbations of the eternal BTZ black hole
Paweł Caputa, Joan Simón, Andrius Štikonas +2
We compute the mutual information between finite intervals in two non-compact 2d CFTs in the thermofield double formulation after one of them has been locally perturbed by a primar…
Notes on Entanglement Entropy in String Theory
Song He, Tokiro Numasawa, Tadashi Takayanagi +1
In this paper, we study the entanglement entropy in string theory in the simplest setup of dividing the nine dimensional space into two halves. This corresponds to the leading quan…
