Selective confinement of macroscopic long-lifetime exciton and trion populations
Confinement of cold macroscopic particle ensembles opens avenues to study many-body coherent states of matter in a controlled environment. We create pure macroscopic cold long-lifetime trion and exciton gases and arbitrary mixtures spatially confined with fabricated electrostatic potentials on GaAs/AlGaAs coupled quantum well structures. The population densities are readily controlled by electric field and laser power. In the exciton phase, we observe a strong contraction of the exciton mode...[Show more]
