摘要: We discuss the implementation of two different truncated Generalized Gibbs Ensembles (GGE) describing stationary state after a mass quench process in Ising Field Theory. One GGE is based on semi-local charges model, other regularized versions its ultra-local charges. test efficiency ensembles by comparing their predictions for values single-particle Green's function $G(x) = \langle \psi^{\dagger}(x) \psi(0) \rangle$ complex fermion field $\psi(x)$. find that both GGEs are able to recover $G(x)$, but given number version performs better.
