Entanglement of several blocks in fermionic chains

Ares, Filiberto ; Esteve, J.G. (Universidad de Zaragoza) ; Falceto, Fernando

Resumen: 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. We check numerically the accuracy of our proposal and conjecture a formula for the asymptotic behavior of principal submatrices of a Toeplitz matrix.
