AI总结:
本文通过大N均场理论研究二维中两个轻费米子与N个重费米子的零程相互作用,发现系统从不完全束缚,总是分裂为单轻原子液滴,与一维情况形成对比。
摘要:
通过发展适用于大N的均场理论,我们研究了二维中两个轻费米子通过零程势与N个重费米子相互作用的问题。我们得到数值证据表明该系统从未完全束缚。它总是分裂成包含单个轻原子的液滴。这与一维情况形成对比,在一维中任意数量的重费米子和轻费米子都可以束缚在一起。
英文摘要:
By developing the mean-field theory valid for large $N$, we investigate the problem of two light fermions interacting via a zero-range potential with $N$ heavy fermions in two dimensions. We obtain numerical evidence that this system is never fully bound. It always splits into droplets containing a single light atom. This is in contrast to the one-dimensional case where any number of heavy and light fermions can be bound together.
