<正>We have studied the ground state configurations of a rotating Bose-Einstein condensation in a toroidal trap as the radius of the central Gaussian potential
<正>With a self-similar parameter b(A_t)=H_i/λ_i,where A_t is the Atwood number,H_i andλ_i are the amplitude and wavelength of bubble(i = 1) and spike(i = 2)
<正>Gauge potential plays an important role in exploring exotic phenomena in the single- and many-body quantum systems.In this paper,we propose a scheme to crea
