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.…

Ehrenfest dynamics is purity non-preserving: a necessary ingredient for decoherence
J. L. Alonso, J. Clemente-Gallardo, J. C. Cuchí +2
We discuss the evolution of purity in mixed quantum/classical approaches to electronic nonadiabatic dynamics in the context of the Ehrenfest model. As it is impossible to exactly d…
