Nonlinear Band Structure in Bose Einstein Condensates: The Nonlinear Schrödinger Equation with a Kronig-Penney Potential
B. T. Seaman, L. D. Carr, M. J. Holland
All Bloch states of the mean field of a Bose-Einstein condensate in the presence of a one dimensional lattice of impurities are presented in closed analytic form. The band structur…

Effect of a potential step or impurity on the Bose-Einstein condensate mean field
B. T. Seaman, L. D. Carr, M. J. Holland
The full set of stationary states of the mean field of a Bose-Einstein condensate in the presence of a potential step or point-like impurity are presented in closed analytic form.…
