Interference dislocations in condensate of indirect excitons
J. R. Leonard, Lunhui Hu, A. A. High +5
Phase singularities in quantum states play a significant role both in the state properties and in the transition between the states. For instance, a transition to two-dimensional s…
Pancharatnam-Berry phase in condensate of indirect excitons
J. R. Leonard, A. A. High, A. T. Hammack +4
We report on the observation of the Pancharatnam-Berry phase in a condensate of indirect excitons (IXs) in a GaAs coupled quantum well structure. The Pancharatnam-Berry phase leads…
Transport of Indirect Excitons in High Magnetic Fields
Y. Y. Kuznetsova, C. J. Dorow, E. V. Calman +4
We present spatially- and spectrally-resolved photoluminescence measurements of indirect excitons in high magnetic fields. Long indirect exciton lifetimes give the opportunity to m…
Fluctuation and Commensurability Effect of Exciton Density Wave
Sen Yang, L. V. Butov, B. D. Simons +2
At low temperatures, indirect excitons formed at the in-plane electron-hole interface in a coupled quantum well structure undergo a spontaneous transition into a spatially modulate…
Nonlinear optical spectroscopy of indirect excitons in biased coupled quantum wells
P. Andreakou, S. Cronenberger, D. Scalbert +9
Indirect excitons in coupled quantum wells are long-living quasi-particles, explored in the studies of collective quantum states. We demonstrate, that despite the extremely low osc…
Pattern Formation in the Exciton Inner Ring
M. Remeika, A. T. Hammack, S. Poltavtsev +6
We report on the spatially separated pump-probe study of indirect excitons in the inner ring in the exciton emission pattern. A pump laser beam generates the inner ring and a weake…
