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…

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…

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…
