Nonlinear Lattice Dynamics of Bose-Einstein Condensates
Mason A. Porter, R. Carretero-González, P. G. Kevrekidis +1
The Fermi-Pasta-Ulam (FPU) model, which was proposed 50 years ago to examine thermalization in non-metallic solids and develop ``experimental'' techniques for studying nonlinear pr…

Bose-Einstein Condensates in Superlattices
Mason A. Porter, P. G. Kevrekidis
We consider the Gross-Pitaevskii (GP) equation in the presence of periodic and quasiperiodic superlattices to study cigar-shaped Bose-Einstein condensates (BECs) in such potentials…
