NUMERICAL SOLUTION OF THREE-WAVE SOLITON EXCITATIONS IN BOSE-EINSTEIN CONDENSATION

摘要：

Based on time-splitting spectral method, a three-wave resonant interaction of collective modes and related soliton excitations in a disk-shaped Bose-Einstein condensate are investigated. The phase-matching conditions for the resonant interaction are satisfied by suitably choosing the wavevectors and the frequencies of the collective modes. A set of nonlinearly coupled envelope equations describing the spatio-temporal evolution of the three-wave resonant interaction are derived by using a method of multiple-scales and some explicit (2+l)-dimensional three-wave soliton solutions are also discussed.
