Description:
Author(s): S. Kumar, A. M. Perego, and K. Staliunas We report on the focalization of Bogoliubov–de Gennes excitations of the nonlinear Schrödinger equation in the defocusing regime (Gross-Pitaevskii equation for repulsive Bose-Einstein condensates) with a spatially modulated periodic potential. Exploiting the modification of the dispersion relation i… [Phys. Rev. Lett. 118, 044103] Published Fri Jan 27, 2017
