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…
Surface/State Correspondence as a Generalized Holography
Masamichi Miyaji, Tadashi Takayanagi
We propose a new duality relation between codimension two space-like surfaces in gravitational theories and quantum states in dual Hilbert spaces. This surface/state correspondence…
