Quantum Chaos, Thermodynamics and Black Hole Microstates in the mass deformed SYK model
Tomoki Nosaka, Tokiro Numasawa
We study various aspects of the mass deformed SYK model which can escape the interiors of pure boundary state black holes. SYK boundary states are given by a simple local boundary…
Double Local Quenches in 2D CFTs and Gravitational Force
Pawel Caputa, Tokiro Numasawa, Teppei Shimaji +2
In this work we extensively study the dynamics of excited states created by instantaneous local quenches at two different points, i.e., double local quenches. We focus on setups in…
Late Time Quantum Chaos of pure states in the SYK model
Tokiro Numasawa
In this letter, we study the return amplitude, which is the overlap between the initial state and the time evolved state, in the Sachdev-Ye-Kitaev (SYK) model. Initial states are t…
Global Spacetime Structure of Compactified Inflationary Universe
Tokiro Numasawa, Daisuke Yoshida
We investigate the global spacetime structure of torus de Sitter universe, which is exact de Sitter space with torus identification based on the flat chart. We show that past incom…
