对于中等库仑能量与费米能量比r_s，无自旋费米子在随机势中形成一个新的量子相，它既不是费米玻璃，也不是维格纳晶体。研究小集群，我们表明，这一阶段引起的无序强度和比率${R}_{S}$，最近已观察到在两个维度的金属相增强持续电流的有序流动。
For intermediate Coulomb energy to Fermi energy ratios ${r}_{s}$, spinless fermions in a random potential form a new quantum phase which is neither a Fermi glass, nor a Wigner crystal. Studying small clusters, we show that this phase gives rise to an ordered flow of enhanced persistent currents for disorder strength and ratios ${r}_{s}$, where a metallic phase has been recently observed in two dimensions.
