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…
