Black Hole Entropy from String Entanglement
Soichiro Mori, Tadakatsu Sakai, Masaki Shigemori
We discuss the notion of string entanglement in string theory, which aims to study entanglement between worldsheet Hilbert spaces rather than entanglement between spacetime Hilbert…

Note on higher-group structure in 6d self-dual gauge theory
Tatsuki Nakajima, Kikyo Nakamura, Tadakatsu Sakai
We analyze higher-group structure of a 6d model coupled with a self-dual 2-form gauge field. This model is defined from 6d axion-electrodynamics with a 1-form Chern-Weil(CW) symmet…
