Phase transitions in a system of indirect magnetoexcitons in coupled quantum wells at high magnetic field: the role of disorder
Oleg L. Berman, Yurii E. Lozovik, David W. Snoke +1
Collective properties of a quasi-two-dimensional (2D) system of spatially indirect magnetoexcitons in coupled quantum wells (CQW) in high magnetic field were analyzed in the pr…
Temperature dependence of exciton Auger decay process in Cuprous Oxide
Yingmei Liu, David Snoke
We report theoretical and experimental study on Auger decay of excitons in Cuprous Oxide in a wide range of temperatures, from 2 Kelvin to 325 Kelvin, in single-photon surface exci…
Elementary Theory of Line Broadening and Four-wave Mixing in Nonequilibrium Many-Particle Systems
David W. Snoke
The basic results of optical line broadening and four-wave mixing are deduced from first principles based on time-dependent many-body purturbation theory. The formalism allows us t…
Controlled Drift of Indirect Excitons in Coupled Quantum Wells: Toward Bose Condensation in a Two-Dimensional Trap
V. Negoita, D. W. Snoke, K. Eberl
We have succeeded in trapping indirect excitons in coupled quantum wells in a harmonic potential minimum via inhomogeneous applied stress and electric field. These excitons exhibit…
