On truncated generalized Gibbs ensembles in the Ising field theory
Journal of Statistical Mechanics: Theory and Experiment IOP Publishing 2017:1 (2017) 013103
Abstract:
We discuss the implementation of two dierent truncated Generalized Gibbs Ensembles (GGE) describing the stationary state after a mass quench process in the Ising Field Theory. One truncated GGE is based on the semi-local charges of the model, the other on regularized versions of its ultra-local charges. We test the efficiency of the two different ensembles by comparing their predictions for the stationary state values of the single-particle Green's function G(x) = ⟨Ψ†(x)Ψ(0)⟩ of the complex fermion field Ψ(x). We find that both truncated GGEs are able to recover G(x), but for a given number of charges the semi-local version performs better.

Eigenstate phase transitions and the emergence of universal dynamics in highly excited states

Abstract:
© 2017 by WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim We review recent advances in understanding the universal scaling properties of non-equilibrium phase transitions in non-ergodic disordered systems. We discuss dynamical critical points (also known as eigenstate phase transitions) between different many-body localized (MBL) phases, and between MBL and thermal phases.
