Charged Entanglement Entropy of Local Operators
Pawel Caputa, Masahiro Nozaki, Tokiro Numasawa
In this work we consider the time evolution of charged Renyi entanglement entropies after exciting the vacuum with local fermionic operators. In order to explore the information co…
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…
Quantum Entanglement of Fermionic Local Operators
Masahiro Nozaki, Tokiro Numasawa, Shunji Matsuura
In this paper we study the time evolution of (Renyi) entanglement entropies for locally excited states in four dimensional free massless fermionic field theory. Locally excited sta…
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…
On the definition of entanglement entropy in lattice gauge theories
Sinya Aoki, Takumi Iritani, Masahiro Nozaki +3
We focus on the issue of proper definition of entanglement entropy in lattice gauge theories, and examine a naive definition where gauge invariant states are viewed as elements of…
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…
