Anderson localization of Bogoliubov excitations on quasi-1D strips
arXiv:1501.07811 · doi:10.1002/andp.201500106
Abstract
Anderson localization of Bogoliubov excitations is studied for disordered lattice Bose gases in planar quasi-one-dimensional geometries. The inverse localization length is computed as function of energy by a numerical transfer-matrix scheme, for strips of different widths. These results are described accurately by analytical formulas based on a weak-disorder expansion of backscattering mean free paths.
