摘要：

The energy, interaction, and optical properties of reversed-spin quasielectrons (QE(R)s) in fractional quantum Hall systems are studied. Based on the short range of the QE(R)-QE(R) repulsion, a partially unpolarized incompressible, v = 4/11 state is postulated within Haldane hierarchy scheme. To describe photoluminescence, a reversed-spin fractionally charged exciton hQE(R) (QE(R) bound to a valence hole h) is predicted. In contrast to its spin-polarized analog, hQE(R) is strongly bound and radiative. (C) 2002 Elsevier Science B.V. All rights reserved.
