Spontaneous coherence of indirect excitons in a trap
Alexander A. High, Jason R. Leonard, Mikas Remeika +3
We report on the emergence of spontaneous coherence in a gas of indirect excitons in an electrostatic trap. At low temperatures, the exciton coherence length becomes much larger th…
Spontaneous Coherence in a Cold Exciton Gas
Alexander A. High, Jason R. Leonard, Aaron T. Hammack +5
Excitons, bound pairs of electrons and holes, form a model system to explore the quantum physics of cold bosons in solids. Cold exciton gases can be realized in a system of indirec…
Spin Texture in a Cold Exciton Gas
A. A. High, A. T. Hammack, J. R. Leonard +5
We report on the observation of a spin texture in a cold exciton gas in a GaAs/AlGaAs coupled quantum well structure. The spin texture is observed around the exciton rings. The obs…
Electrostatic Conveyer for Excitons
A. G. Winbow, J. R. Leonard, M. Remeika +9
We report on the study of indirect excitons in moving lattices - conveyers created by a set of AC voltages applied to the electrodes on the sample surface. The wavelength of this m…
