Approximate light cone effects in a non-relativistic quantum field theory after a local quench
Bruno Bertini
We study the spreading of correlations after a local quench in a non-relativistic quantum field theory. We focus on noninteracting non-relativistic fermions and study the time evol…
Thermalization and light cones in a model with weak integrability breaking
Bruno Bertini, Fabian H. L. Essler, Stefan Groha +1
We employ equation of motion techniques to study the non-equilibrium dynamics in a lattice model of weakly interacting spinless fermions. Our model provides a simple setting for an…
Transport in Out-of-Equilibrium XXZ Chains: Exact Profiles of Charges and Currents
Bruno Bertini, Mario Collura, Jacopo De Nardis +1
We consider the non-equilibrium time evolution of piecewise homogeneous states in the XXZ spin-1/2 chain, a paradigmatic example of an interacting integrable model. The initial sta…
Determination of the Nonequilibrium Steady State Emerging from a Defect
Bruno Bertini, Maurizio Fagotti
We consider the non-equilibrium time evolution of a translationally invariant state under a Hamiltonian with a localized defect. We discern the situations where a light-cone spread…
Quantum quenches in the sinh-Gordon model: steady state and one point correlation functions
Bruno Bertini, Lorenzo Piroli, Pasquale Calabrese
We consider quantum quenches to the sinh-Gordon integrable quantum field theory from a particular class of initial states. Our analysis includes the case of mass and interaction qu…
