Charges and currents in quantum spin chains: late-time dynamics and spontaneous currents
Maurizio Fagotti
We review the structure of the conservation laws in noninteracting spin chains and unveil a formal expression for the corresponding currents. We briefly discuss how interactions af…
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…
Quench dynamics and relaxation in isolated integrable quantum spin chains
Fabian H. L. Essler, Maurizio Fagotti
We review the dynamics after quantum quenches in integrable quantum spin chains. We give a pedagogical introduction to relaxation in isolated quantum systems, and discuss the descr…
Entanglement growth and correlation spreading with variable-range interactions in spin and fermionic tunnelling models
Anton S. Buyskikh, Maurizio Fagotti, Johannes Schachenmayer +2
We investigate the dynamics following a global parameter quench for two 1D models with variable-range power-law interactions: a long-range transverse Ising model, which has recentl…
Local conservation laws in spin-1/2 XY chains with open boundary conditions
Maurizio Fagotti
We revisit the conserved quantities of the spin-1/2 XY model with open boundary conditions. In the absence of a transverse field, we find new families of local charges and show tha…
