Superfluid Dynamics of a Bose-Einstein Condensate in a Periodic Potential
C. Menotti, A. Smerzi, A. Trombettoni
We investigate the superfluid properties of a Bose-Einstein condensate (BEC) trapped in a one dimensional periodic potential. We study, both analytically (in the tight binding limi…

Nonlinear Tight-Binding Approximation for Bose-Einstein Condensates in a Lattice
Augusto Smerzi, Andrea Trombettoni
The dynamics of Bose-Einstein condensates trapped in a deep optical lattice is governed by a discrete nonlinear equation (DNL). Its degree of nonlinearity and the intersite hopping…
