The Fractional Quantum Hall Effect

这项提议代表了分数量子霍尔效应(FQHE)研究的继续，FQHE最初是NSF的一项产学合作研究活动，涉及与AT&Amp；T Bell实验室的H.L.Stormer博士的合作。这项拟议的研究代表了FQHE努力的继续，并将集中在三个领域，即1)基态的性质，2)低能量激发，以及3)向Wigner固体的转变。近年来，这个研究小组在这一子领域取得了许多重大发现，在过去三年的时间里，观察到了FQHE系列的偶分母态、小填充因子终止、QHE的标度行为，并获得了关于准粒子能隙的重要新信息。

This proposal represents a continuation of research on the fractional quantum Hall effect (FQHE), which started as a NSF Industry-University Cooperation Research Activity and involved a collaboration with Dr. H. L. Stormer of AT&T Bell Labs. The proposed research represents a continuation of the FQHE effort and will be concentrated in three areas, namely 1) the nature of the ground state, 2) low energy excitations, and 3) the transition to a Wigner solid. This research team has made many of the significant discoveries in recent years in this subfield and in the last 3-year period observed the even denominator state, the small filling factor termination of the FQHE series, the scaling behavior of the QHE, and obtained important new information on the quasi-particle gaps.
