论文摘要
量子流体中相对充满电的光涡流的自我否决受到非线性的阻碍，并由径向限制促进，从而导致了这种对的丰富生命周期动力学。竞争效应产生了一个可以直接与原始对相互作用的外围涡旋生物群体，以产生一系列代理事件。数值模拟用于阐明涡流生物群落作为非线性强度的函数以及工程涡流之间的初始间距。该结果也直接适用于其他非线性量子流体，并且可能在控制涡流动力学产生拓扑保护相的复杂冷凝物的控制中有用。
The self-annihilation of oppositely charged optical vortices in a quantum fluid is hindered by nonlinearity and promoted by radial confinement, resulting in rich life-cycle dynamics of such pairs. The competing effects generate a biome of peripheral vortices that can directly interact with the original pair to produce a sequence of surrogation events. Numerical simulation is used to elucidate the role of the vortex biome as a function of nonlinearity strength and the initial spacing between the engineered vortices. The results apply directly to other nonlinear quantum fluids as well and may be useful in the control of complex condensates in which vortex dynamics produce topologically protected phases.
