Entanglement of several blocks in fermionic chains
arXiv:1406.1668 · doi:10.1103/PhysRevA.90.062321
Abstract
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 new formula for the asymptotic behaviour of principal sub-matrices of a Toeplitz matrix.
