论文摘要
我们从理论上检查了受捕获的准二维超电压玻色子的气体的涡旋状态，受到密度依赖量规的电势，实现了原子冷凝物的有效非线性旋转，我们也表明，这也显示了具有超级原子能实验的当前实验技术的范围。非线性旋转具有两倍的效果。除了扭曲冷凝水的形状外，它还导致不均匀的涡度，导致新型的形态和拓扑状态，包括不遵循标准的Abrikosov结果的环涡式排列。还探索了被困涡流的动力学，这与由于没有全球实验室参考框架而导致的刚体旋转的情况不同。
We theoretically examine the vortex states of a gas of trapped quasi-two-dimensional ultracold bosons subject to a density-dependent gauge potential, realizing an effective nonlinear rotation of the atomic condensate, which we also show is within the reach of current experimental techniques with ultracold atom experiments. The nonlinear rotation has a two-fold effect; as well as distorting the shape of the condensate it also leads to an inhomogeneous vorticity resulting in novel morphological and topological states, including ring vortex arrangements that do not follow the standard Abrikosov result. The dynamics of trapped vortices are also explored, which differs from the case of rigid-body rotation due to the absence of a global laboratory reference frame.
