一个快速旋转的玻色-爱因斯坦凝聚体被限制在一个二次加四次势中,动态地产生一个“巨涡”,将所有的相位奇异性吸收到中心的低密度孔中,从而维持一个准一维的超音速圆形超流。
A fast rotating Bose-Einstein condensate confined in a quadratic-plus-quartic potential is found to dynamically generate a "giant vortex" that absorbs all phase singularities into a central low density hole, thereby sustaining a quasi-one-dimensional circular superflow at a supersonic speed.
