A theory of anyon excitons consisting of a valence hole and three quasielectrons with electric charges –e/3 is presented. A full symmetry classification of the k = 0 states is given, where k is the exciton momentum. The energy levels of these states are expressed by quadratures of confluent hypergeometric functions. It is shown that the angular momentum L of the exciton ground state depends on the distance between the electron and hole confinement planes and takes the values L = 3n, where n is an integer. With increasing k the electron density shows a spectacular splitting on bundles. At first a single anyon splits off of the two-anyon core, and finally all anyons become separated.
The connection between luminescence and different chapters of spectroscopy is discussed. Modern theoretical concepts and experimental techniques wiped away the boundaries that traditionally existed between them. Nevertheless, the basic notions of luminescence remain valid. Being focused on the dynamics and kinetics of electronically excited states, luminescence serves as an effective tool in solving numerous problems in contemporary solid-state physics. Electron–phonon interaction, excitons in disordered systems, the emission spectroscopy of the fractional quantum Hall effect and spin injection are discussed as specific examples.
