Finite-size corrections vs. relaxation after a sudden quench
Maurizio Fagotti
We consider the time evolution after sudden quenches of global parameters in translational invariant Hamiltonians and study the time average expectation values and entanglement ent…
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…
Quantum Quench in the Transverse Field Ising Chain II: Stationary State Properties
Pasquale Calabrese, Fabian H. L. Essler, Maurizio Fagotti
We consider the stationary state properties of the reduced density matrix as well as spin-spin correlation functions after a sudden quantum quench of the magnetic field in the tran…
Quantum Quench in the Transverse Field Ising chain I: Time evolution of order parameter correlators
P. Calabrese, F. H. L. Essler, M. Fagotti
We consider the time evolution of order parameter correlation functions after a sudden quantum quench of the magnetic field in the transverse field Ising chain. Using two novel met…
