Faraday waves in cold-atom systems with two- and three-body interactions

We report an investigation on Bose-Einstein condensates with two-body (cubic) and three-body (quintic) interactions in the corresponding nonlinear Schrodinger equation, considering s-wave two-body scattering length as periodically varying in time. For the quintic interacting term, the dependence on...

For the quintic interacting term, the dependence on as was considered within two models, being quadratic or quartic.
