Title: Collective phenomena in cold indirect excitons

Abstract

Due to their long lifetimes, indirect excitons can cool to below the temperature of quantum degeneracy. This gives an opportunity to experimentally study cold composite bosons. Both theoretically predicted phenomena and phenomena that have not been anticipated were observed in a cold gas of indirect excitons. In this contribution, we overview our studies of cold indirect excitons over the past decade, presenting spontaneous coherence and condensation of excitons, spatially modulated exciton state, long-range spin currents and spin textures, and exciton localization–delocalization transitions.

  • We theoretically analyze a quasi-two-dimensional system of fermionic polar molecules trapped in a harmonic transverse confining potential. The renormalized energy bands are calculated by solving the Hartree-Fock equation numerically for various trap and dipolar interaction strengths. The intersubband excitations of the system are studied in the conserving time-dependent Hartree-Fock (TDHF) approximation from the perspective of lattice modulation spectroscopy experiments. We find that the excitation spectrum consists of both intersubband particle-hole excitation continua and antibound excitons whose antibinding behavior is associated to the anisotropic nature of dipolar interactions. The excitonic modes are shown to capture the majority of the spectral weight.more » We evaluate the intersubband transition rates in order to investigate the nature of the excitonic modes and find that they are antibound states formed from particle-hole excitations arising from several subbands. We discuss the sum rules in the context of lattice modulation spectroscopy experiments and utilize them to check the consistency of the obtained results. Our results indicate that the excitonic effects persist for interaction strengths and temperatures accessible in the current experiments with polar molecules.« less
  • We observe and analyze strongly nonlinear photoluminescence kinetics of indirect excitons in GaAs/AlGaAs coupled quantum wells at low bath temperatures, {ge}50 mK . The long recombination lifetime of indirect excitons promotes accumulation of these Bose particles in the lowest energy states and allows the photoexcited excitons to cool down to temperatures where the dilute 2D gas of indirect excitons becomes statistically degenerate. Our main result{emdash}a strong enhancement of the exciton scattering rate to the low-energy states with increasing concentration of the indirect excitons{emdash}reveals bosonic stimulation of exciton scattering, which is a signature of a degenerate Bose-gas of excitons.
  • This paper investigates the luminescence properties of the indirect solid solutions of In /SUB 1-x/ Ga /SUB x/ P obtained at high levels of excitation. The luminescence properties were obtained using the cathode luminescence technique. The complex luminescence band that arises for sufficiently high levels of excitation at T = 9 K is attributed to the luminescence of an electron-hole drop. The transformation of spectral form of the EHD band with the transition from GaP to In /SUB 1-x/ Ga /SUB x/ P is attributed to a simultaneous reduction in the contribution of the TA and TO replicas and tomore » the appearance of a phononless component in the luminescence of the electron-hole drop.« less
