论文摘要
我们研究了限制在环中的两个量子颗粒的特性。颗粒通过远程规格电位与颗粒之间的距离成正比相互作用。发现两体基态对应于具有非零角动量的状态，前提是颗粒之间的相互作用足够强。另外，粒子的相关性是从相互作用强度的不同意义上相关的。我们讨论了测量其中一个颗粒位置并从环中去除粒子的效果，在那里我们表明剩余的粒子可以在非分散性状态下以非零角动量制备。
We study the properties of two quantum particles which are confined in a ring. The particles interact via a long-range gauge potential proportional to the distance between the particles. It is found that the two-body ground state corresponds to a state with non-zero angular momentum provided that the interaction between the particles is strong enough. In addition, the particles are correlated in the sense that depending on the interaction strength there is a propensity to be found close together or separated in the ring. We discuss the effect of measuring the position of one of the particles and thereby removing the particle from the ring, where we show that the remaining particle can be prepared in a non-dispersive state with non-zero angular momentum.
