Läuchli, Andreas M. and Schliemann, John (2012) Entanglement spectra of coupled S=1/2 spin chains in a ladder geometry. Phys. Rev. B 85, 054403.
We study the entanglement spectrum of spin-1/2 XXZ ladders both analytically and numerically. Our analytical approach is based on perturbation theory starting either from the limit of strong rung coupling, or from the opposite case of dominant coupling along the legs. In the former case we find to leading order that the entanglement Hamiltonian is also of nearest-neighbor XXZ form although with ...
