The Quantum Hall and Fractional Quantum Hall Effects
1992The range of phenomena observed in electronic systems in magnetic fields is large and spectacular. Perhaps most spectacular of all are the quantum Hall effect (QHE) and fractional quantum Hall effect. This chapter is concerned with the theoretical description of these phenomena.

Fractional Quantum Hall Effect: Introduction
1995The FQHE was realized in high-mobility 2DEG in GaAs/Al x Ga1-x As heterostructures [4.1–6] and in high-mobility Si-MOSFETs [4.7]. It is characterized by the fact that the Hall conductance has plateaus quantized to certain simple fractions v of the unit e 2 / h and at the same places, the longitudinal resistivity shows an almost dissipationless current ...

Quantum Hall Effect: Fractional Quantization
1985The quantum Hall effect is a new physical phenomenon, characterized by the fact that the Hall conductance is quantized to GH = ie2/h, where e is the electronic charge, h is Planck’s constant, and the quantum number i is an integer, for integral quantization, and an odd-denominators fraction, for fractional quantization.

The Fractional Quantum Hall Effect
2002The existence of an energy gap is essential for the fractional quantum Hall effect (FQHE). However, in the case of the FQHE, the origin of the gap is different from that in the case of the IQHE. In the latter, the gap already exists in the single-electron spectrum. However, in the former we need a gap that appears as a consequence of the mutual Coulomb

Quasiexcitons in the fractional quantum Hall effect
Physical Review B, 1994The spherical version of Laughlin's quasiexciton wave functions at \ensuremath{\nu}=1/m, which were originally constructed in planar geometry, is formulated, and extended to other filling factors. It is shown that the quasiexciton wave functions are rather accurate in describing the low-lying excitations.
