On truncated generalized Gibbs ensembles in the Ising field theory
<p>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-...

| description | <p>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 <i>G(x) = ⟨Ψ<sup>†</sup>(x)Ψ(0)⟩</i> of the complex fermion field <i>Ψ(x)</i>. We find that both truncated GGEs are able to recover <i>G(x)</i>, but for a given number of charges the semi-local version performs better.</p> |
