Out-of-equilibrium inhomogeneous XX chains: Exact results and the hydrodynamic limit
Vincenzo Alba, Federico Rottoli
We study the out-of-equilibrium dynamics in the XX chain with step-like magnetic field, which maps to an inhomogeneous tight-binding chain after Jordan-Wigner transformation. We ob…
Entanglement dynamics after quenches with inhomogeneous Hamiltonians
Andrea Di Pasquale, Federico Rottoli, Vincenzo Alba
We investigate entanglement dynamics in bipartite systems governed by inhomogeneous Hamiltonians of the form , where acts only on the left or right region…
Eigenstate Thermalization Hypothesis (ETH) for off-diagonal matrix elements in integrable spin chains
Federico Rottoli, Vincenzo Alba
We investigate off-diagonal matrix elements of local operators in integrable spin chains, focusing on the isotropic spin- Heisenberg chain ( chain). We employ state-of-th…
Universality of equilibration dynamics after quantum quenches
Vincenzo Alba, Sanam Azarnia, Gianluca Lagnese +1
We investigate the distribution of the eigenvalues of the reduced density matrix (entanglement spectrum) after a global quantum quench. We show that in an appropriate scaling limit…
