摘要：
We present a new family of analytic solutions of the nonlinear Schrodinger equation with an imaginary potential that describes the dynamics of a bright soliton in a Bose-Einstein condensate with an expulsive parabolic and complex potential. We found that under a safe range of parameters, the bright soliton can be compressed into very high local matter densities by increasing the value of the feeding parameter.
