Finite entangling regions and information paradox in charged black holes
Aleksandr I. Belokon
In this paper, we study the influence of the electric charge of Reissner-Nordstrom black hole on the dynamics of fine-grained entropy of Hawking radiation, collected in finite enta…

Local quenches in fracton field theory: Lieb-Robinson bound, non-causal dynamics and fractal excitation patterns
Dmitry S. Ageev, Andrey A. Bagrov, Aleksandr I. Belokon +3
We study the out-of-equilibrium dynamics induced by a local perturbation in fracton field theory. For the and -symmetric free fractonic theories, we…

Entanglement entropy in de Sitter: no pure states for conformal matter
D. S. Ageev, I. Ya. Aref'eva, A. I. Belokon +2
In this paper, we consider the entanglement entropy of conformal matter for finite and semi-infinite entangling regions, as well as the formation of entanglement islands in four-di…
