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…
Entanglement Hamiltonians in dissipative free fermions and the time-dependent GGE
Riccardo Travaglino, Federico Rottoli, Pasquale Calabrese
We investigate the dynamics of Entanglement Hamiltonians (EHs) in dissipative free-fermionic systems using a recent operator-based formulation of the quasiparticle picture. Focusin…
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…
Time Evolution of the Symmetry Resolved Entanglement Entropy after a Mass Quench
Federico Rottoli, Michele Mazzoni, Fabio Sailis +1
In this paper we investigate the properties of the symmetry resolved entanglement entropy after a mass quench in the Ising field theory. Since the theory is free and the post-quenc…
Entanglement Hamiltonians and the quasiparticle picture
Federico Rottoli, Colin Rylands, Pasquale Calabrese
The entanglement Hamiltonian (EH) provides the most comprehensive characterization of bipartite entanglement in many-body quantum systems. Ground states of local Hamiltonians inher…
Entanglement Hamiltonian in the non-Hermitian SSH model
Federico Rottoli, Michele Fossati, Pasquale Calabrese
Entanglement Hamiltonians provide the most comprehensive characterisation of entanglement in extended quantum systems. A key result in unitary quantum field theories is the Bisogna…
Entanglement entropy along a massless renormalisation flow: the tricritical to critical Ising crossover
Federico Rottoli, Filiberto Ares, Pasquale Calabrese +1
We study the Rényi entanglement entropies along the massless renormalisation group flow that connects the tricritical and critical Ising field theories. Similarly to the massive in…
Finite temperature negativity Hamiltonians of the massless Dirac fermion
Federico Rottoli, Sara Murciano, Pasquale Calabrese
The negativity Hamiltonian, defined as the logarithm of a partially transposed density matrix, provides an operatorial characterisation of mixed-state entanglement. However, so far…
Entanglement and negativity Hamiltonians for the massless Dirac field on the half line
Federico Rottoli, Sara Murciano, Erik Tonni +1
We study the ground-state entanglement Hamiltonian of several disjoint intervals for the massless Dirac fermion on the half-line. Its structure consists of a local part and a bi-lo…
Domain wall melting across a defect
Luca Capizzi, Stefano Scopa, Federico Rottoli +1
We study the melting of a domain wall in a free-fermionic chain with a localised impurity. We find that the defect enhances quantum correlations in such a way that even the smalles…
Entanglement Hamiltonian during a domain wall melting in the free Fermi chain
Federico Rottoli, Stefano Scopa, Pasquale Calabrese
We study the unitary time evolution of the entanglement Hamiltonian of a free Fermi lattice gas in one dimension initially prepared in a domain wall configuration. To this aim, we…
