|Issue Date:||Jan-2010||Citation:||Hide, J., Vedral, V. (2010-01). Entanglement in disordered and non-equilibrium systems. Physica E: Low-Dimensional Systems and Nanostructures 42 (3) : 359-362. ScholarBank@NUS Repository. https://doi.org/10.1016/j.physe.2009.06.073||Abstract:||We calculate an entanglement witness for a disordered spin system using the method of functional many-body perturbation theory, comparing the effect of taking a quenched and an annealed average over the disorder. We find, on considering the example of an XX Heisenberg spin chain with a Dzyaloshinskii-Moriya interaction, that disorder in the Dzyaloshinskii-Moriya interaction increases the region of entanglement detected by the witness. We also discuss a method of detecting entanglement in far from equilibrium systems. © 2009 Elsevier B.V.
