论文摘要
我们介绍了光子冷凝阵列中涡流的理论研究。即使相互作用可以忽略不计,就像当前的实验一样,抽水和损耗也会导致有限的涡流核心大小。虽然光子凝结涡旋的某些特性,例如它们的自我加速和通过移动的涡流产生涡旋对的产生,类似于相互作用的极性凝结的人,在几个方面与先前研究的系统不同,它们与先前研究的系统不同:涡流核心的大小是由泵和核心构成的构成,而核心的构成是在泵和隧道中构成的,而构成了新的构成。 地区。
We present a theoretical study of vortices in arrays of photon condensates. Even when interactions are negligible, as is the case in current experiments, pumping and losses can lead to a finite vortex core size. While some properties of photon condensate vortices, such as their self-acceleration and the generation of vortex pairs by a moving vortex, resemble those in interacting polariton condensates far from equilibrium, in several aspects they differ from previously studied systems: the vortex core size is determined by the balance between pumping and tunneling, the core appears oblate in the direction of its motion and new vortex pairs can spontaneously nucleate in the core region.
