Information scrambling, which is the spread of local information through a system's many-body degrees freedom, an intrinsic feature dynamics. In quantum systems, out-of-time-ordered correlator (OTOC) quantifies scrambling. Motivated by experiments that have measured OTOC at infinite temperature and theory proposal to measure finite using thermofield double state, we describe protocol in spin ch...

Group field theories are higher-rank generalizations of matrix/tensor models, and encode the simplicial geometries quantum gravity. In this paper, we study thermofield double states in group theories. The starting point is equilibrium Gibbs theory recently found by Kotecha Oriti, based on which construct state as a “thermal” vacuum respecting Kubo–Martin–Schwinger condition. We work with Weyl [...

A bstract We present a novel framework for simulating matrix models on quantum computer. Supersymmetric have natural applications to superstring/M-theory and gravitational physics, in an appropriate limit of parameters. Furthermore, certain states the Berenstein-Maldacena-Nastase (BMN) model, several supersymmetric field theories dual can be realized device. Our prescription consists four steps...
