Description:
Author(s): H. Francis Song, Nicolas Laflorencie, Stephan Rachel, and Karyn Le Hur We compute the von Neumann and generalized Rényi entanglement entropies in the ground-state of the spin- 1/2 antiferromagnetic Heisenberg model on the square lattice using the modified spin-wave theory for finite lattices. The addition of a staggered magnetic field to regularize the zero modes associ... [Phys. Rev. B 83, 224410] Published Tue Jun 21, 2011
