【报告摘要】The PT-symmetric Gross-Pitaevskii(GP) equation is presented, which is an important and useful model in Bose-Einstein condensation(BEC). The generalized Gross-Pitaevskii(GGP(n,n)) equation has several kinds of potentials including Gaussian, harmonic and radial potentials, and it is a generalization GP equation. Then, some physically relevant solutions are derived, a kind of flat-top soliton solution is considered for the nonautonomous GGP(n,n) equation with Gaussian-harmonic-radial PT-symmetric potential. Especially, some novel flattop bright(FTB) soli-tons are found, these FTB solitons can exist stably with Gaussian-harmonic-radial PT-symmetric potentials in a broad range.
