models in AdS spaces at zero and finite temperature. Following the method used in [15], we …

Target space entanglement in quantum mechanics of fermions and matrices

S Sugishita - Journal of High Energy Physics, 2021 - Springer
A bstract We consider entanglement of first-quantized identical particles by adopting an
algebraic approach. In particular, we investigate fermions whose wave functions are given …

On partition functions and phases of scalars in AdS

A Kakkar, S Sarkar - Journal of High Energy Physics, 2022 - Springer
A bstract We study the phases of scalar field theories in thermal AdS d+ 1 spaces for d= 1, 2,

Entanglement entropy for free scalar fields in AdS

S Sugishita - Journal of High Energy Physics, 2016 - Springer
A bstract We compute entanglement entropy for free massive scalar fields in anti-de Sitter
(AdS) space. The entangling surface is a minimal surface whose boundary is a sphere at the …

Aharonov-Bohm effect on entanglement entropy in conformal field theory

N Shiba - Physical Review D, 2017 - APS
We consider the Aharonov-Bohm effect on entanglement entropy for one interval in (1+ 1)
dimensional conformal field theory on a one dimensional ring. The magnetic field is confined …

Direct calculation of mutual information of distant regions

N Shiba - Journal of High Energy Physics, 2020 - Springer
A bstract We consider the (Rényi) mutual information,\({I}^{(n)}\left (A, B\right)={S}
_A^{(n)}+{S} _B^{(n)}-{S} _ {A\cup B}^{(n)}\), of distant compact spatial regions A and B in the …

Effects of non-conformal boundary on entanglement entropy

A Loveridge - Journal of High Energy Physics, 2020 - Springer
A bstract Spacetime boundaries with canonical Neuman or Dirichlet conditions preserve
conformal invarience, but “mixed” boundary conditions which interpolate linearly between …

Entanglement Entropy Evolution under Double‐trace Deformation

Y Song - Fortschritte der Physik, 2017 - Wiley Online Library
In this paper, we study the bulk entanglement entropy evolution in conical BTZ black bole
background using the heat kernel method. This is motivated by exploring the new examples …
