Main Article Content



The work conducted in this study is based on the two-dimensional nonlinear Schrodinger equation, which explored asymmetric soliton-like behavior in two-dimensional Bose-Einstein condensate trapped in external harmonic potential. Using the modified variational method, we derived the dynamic
evolution behavior of soliton-like breathing mode with asymmetric features. Our theoretical results can be used as a guide for further experimental research of asymmetric soliton-like behavior in a two-dimensional Bose-Einstein condensate.
