Quantum Correlations in Field Theory and Integrable Systems
Stefano Evangelisti
In this PhD thesis we investigate some properties of one-dimensional quantum systems, focusing on two important aspects of integrable models: Their entanglement properties at equil…
Dynamical Correlations after a Quantum Quench
Fabian H. L. Essler, Stefano Evangelisti, Maurizio Fagotti
In many integrable models static (equal time) correlation functions of local observables after a quantum quench relax to stationary values, which are described by a generalized Gib…
Essential singularity in the Renyi entanglement entropy of the one-dimensional XYZ spin-1/2 chain
Elisa Ercolessi, Stefano Evangelisti, Fabio Franchini +1
We study the Renyi entropy of the one-dimensional XYZ spin-1/2 chain in the entirety of its phase diagram. The model has several quantum critical lines corresponding to rotated XXZ…
