Resonant and non-resonant modulated amplitude waves for binary Bose–Einstein condensates in optical lattices
System the potential coupling nonlinear linear bose-einstein condensate the resonant electromagnetic fields

We consider a system of two Gross–Pitaevskii (GP) equations, in the presence of an optical-lattice (OL) potential, coupled by both nonlinear and linear terms. This system describes a Bose–Einstein con...
Modulated amplitude waves in collisionally inhomogeneous Bose–Einstein condensates

We investigate the dynamics of an effectively one-dimensional Bose–Einstein condensate (BEC) with scattering length a subjected to a spatially periodic modulation, a=a(x)=a(x+L). This “collisionally i...
