Entanglement of several blocks in fermionic chains
F. Ares, J. G. Esteve, F. Falceto
In this paper we propose an expression for the entanglement entropy of several intervals in a stationary state of a free, translational invariant Hamiltonian in a fermionic chain.…

Excited state entanglement in homogeneous fermionic chains
F. Ares, J. G. Esteve, F. Falceto +1
We study the Renyi entanglement entropy of an interval in a periodic fermionic chain for a general eigenstate of a free, translational invariant Hamiltonian. In order to analytical…

Boundary contributions to the hypervirial theorem
J. G. Esteve, F. Falceto, Pulak Ranjan Giri
It is shown that under certain boundary conditions the virial theorem has to be modified. We analyze the origin of the extra term and compute it in particular examples. The Coulomb…
