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…
