论文摘要
我们分析了与短距离两体相互作用的无自旋低维费物的最简单的galilean-varariant模型的零温度通用性能。特别是，表明耦合常数的正确重新归一化后，即使稀释系统也具有丰富的相图，其中包括超流体状态和亚稳态的“上部分支”行为。
We analyze zero-temperature universal properties of the simplest Galilean-invariant model of spinless low-dimensional fermions with short-range two-body interactions. In particular, it is shown that after proper renormalization of the coupling constant, even the dilute system possesses rich phase diagram that includes the superfluid state and the metastable `upper branch' behavior.
