Connecting the von Neumann and Renyi entropies for Fermions [PDF]
Mark Fannes, Nicholas Van RynWe explore the relation between the von Neumann entropy and the Renyi entropies of integer orders for shift-invariant quasi-free Fermionic lattice systems. We investigate approximating the von Neumann entropy by a combination of integer-order Renyi entropies and give an estimate for the quality of such an approximation.View original: http://arxiv.org/abs/1205.0945
