摘      要：The ground state of a rotating Bose-Einstein condensate with attractive interaction in a quasi-one-dimensional torus is studied in terms of the ratio γ of the mean-field interaction energy per particle to the single-particle energy-level spacing. The plateaus of quantized circulation are found to appear if and only if γ1 with the lengths of the plateaus reduced due to hybridization of the condensate over different angular-momentum states.
