考虑了第一朗道能级上电子间的短程相互作用。在这个模型的框架下,Laughlin波函数被证明是精确的。基态能量具有奇异性,作为填充nu的函数,nu =1/m,其中m是奇数。相应的基态是非简并的。
A short-range interaction between electrons on the first Landau level is considered. In the framework of this model the Laughlin-wave-function is shown to be exact. The ground-state energy has singularities as a function of filling nu at nu =1/m, where m is an odd integer. The corresponding ground states are non-degenerate.
