Abstract
The effect of anisotropy on the decay rates and the bifurcation diagram was discussed. Newton and inverse Arnoldi methods were used to investigate nonisotropic attractive Bose-Einstein condensates numerically. The processes considered were macroscopic quantum tunneling, thermally induced collapse, and two-three-body inelastic collisions. It was found that spontaneous isotropization of the condensates occurred.
