Relaxation after quantum quenches in the spin-1/2 Heisenberg XXZ chain
Maurizio Fagotti, Mario Collura, Fabian H. L. Essler +1
We consider the time evolution after quantum quenches in the spin-1/2 Heisenberg XXZ quantum spin chain with Ising-like anisotropy. The time evolution of short-distance spin-spin c…
Dynamical Phase Transitions as Properties of the Stationary State: Analytic Results after Quantum Quenches in the Spin-1/2 XXZ Chain
Maurizio Fagotti
The (Loschmidt) overlap between the state at different times after a quantum quench is attracting increasing interest, as it was recently shown that in the thermodynamic limit its…
Stationary behaviour of observables after a quantum quench in the spin-1/2 Heisenberg XXZ chain
Maurizio Fagotti, Fabian H. L. Essler
We consider a quantum quench in the spin-1/2 Heisenberg XXZ chain. At late times after the quench it is believed that the expectation values of local operators approach time-indepe…
Reduced Density Matrix after a Quantum Quench
Maurizio Fagotti, Fabian H. L. Essler
We consider the reduced density matrix (RDM) ρ_A(t) for a finite subsystem A after a global quantum quench in the infinite transverse-field Ising chain. It has been recently shown…
