分数量子霍尔效应与涡旋晶格。II

Fractional Quantum Hall Effect and vortex lattices.II

S. V. Iordanski, D. S. Lubshin

摘要:

它表明,所有观察到的分数在中等朗道能级填充的量子霍尔效应可以得到没有求助于复合费米子的唯象概念。考虑了具有特殊拓扑非平凡多电子波函数的可能性。它们的族分类表明基态和激发态之间有一个能隙,基态的电子密度具有特殊的值。这些间隙是在简化模型中针对某些晶格计算的。

英文摘要:

It is demonstrated that all observed fractions at moderate Landau level fillings for the quantum Hall effect can be obtained without recourse to the phenomenological concept of composite fermions. The possibility to have the special topologically nontrivial many-electron wave functions is considered. Their group classification indicates the special values of of electron density in the ground states separated by a gap from excited states. These gaps were calculated for some lattices in a simplified model.
