Long Range Ballistic Motion and Coherent Flow of Long Lifetime Polaritons
Mark Steger, Gangqiang Liu, Bryan Nelsen +5
Exciton-polaritons can be created in semiconductor microcavities. These quasiparticles act as weakly interacting bosons with very light mass, of the order of times the va…
Coherent Flow and Trapping of Polariton Condensates with Long Lifetime
Bryan Nelsen, Gangqiang Liu, Mark Steger +4
We report new results of Bose-Einstein condensation of polaritons in specially designed microcavities with very high quality factor, on the order of , giving the polariton li…
The role of the stress trap in polariton quasiequilibrium condensation in GaAs microcavities
R. Balili, B. Nelsen, D. W. Snoke +2
Recent experiments have shown several effects indicative of Bose-Einstein condensation in polaritons in GaAs-based microcavity structures when a harmonic potential trap for the two…
Actively Tuned and Spatially Trapped Polaritons
R. B. Balili, D. W. Snoke, L. Pfeiffer +1
We report active tuning of the polariton resonance of quantum well excitons in a semiconductor microcavity using applied stress. Starting with the quantum well exciton energy highe…
Long-Distance Diffusion of Excitons in Double Quantum Well Structures
Z. Vörös, R. Balili, D. W. Snoke +2
In this Letter we report on lateral diffusion measurements of excitons at low temperature in double quantum wells of various widths. The structure is designed so that excitons live…
