Product of Random States and Spatial (Half-)Wormholes
Kanato Goto, Yuya Kusuki, Kotaro Tamaoka +1
We study how coarse-graining procedure of an underlying UV-complete quantum gravity gives rise to a connected geometry. It has been shown, quantum entanglement plays a key role in…

Aspects of Pseudo Entropy in Field Theories
Ali Mollabashi, Noburo Shiba, Tadashi Takayanagi +2
In this article, we explore properties of pseudo entropy [1] in quantum field theories and spin systems from several approaches. Pseudo entropy is a generalization of entanglement…

Observing black holes through holographic superconductors
Youka Kaku, Keiju Murata, Jun Tsujimura
We propose a way to observe the photon ring of the asymptotically anti-de Sitter black hole dual to a superconductor on the two-dimensional sphere. We consider the electric current…
