Abstract
Here we show, by performing ab initio classical field simulations that two distinct superfluid phases, separated by thermal vortex-antivortex pair creation, exist in experimentally producible quasi-2D Bose gas. These results resolve the debate on the nature of the low temperature phase(s) of a trapped interacting 2D Bose gas.
摘要
在这里，我们通过进行从头算经典场模拟表明，在实验可制备的准二维玻色气体中存在由热涡旋-反涡旋对产生所分隔的两个不同的超流相。这些结果解决了关于捕获的相互作用二维玻色气体低温相性质的争论。
