Abstract
A fast, explicit time-marching scheme is used for the solution of the Gross-Pitaevskii equation in cylindrical geometry. Scheme validity is analyzed using simple analytical tests and is demonstrated for two situations of physical interest on the Bose-Einstein condensation (BEC) of trapped alkali-metal vapors. This is tested using reproduced results on the free expansion of a BEC after removing a cylindrical trap.File in questo prodotto:
