Journal ArticleDOI
Erratum: Polariton dispersion of periodic quantum well structures (Pis’ma Zh. Éksp. Teor. Fiz. 76, 739 (2002) [JETP Lett. 76, 637 (2002)])
Journal ArticleDOI
Macroscopically ordered state in an exciton system
TL;DR: Photoluminescence measurements of a quasi-two-dimensional exciton gas in GaAs/AlGaAs coupled quantum wells and the observation of a macroscopically ordered exciton state are reported.
Journal ArticleDOI
High-temperature superfluidity with indirect excitons in van der Waals heterostructures
TL;DR: A design for artificially structured materials to rival the present record for high-critical temperature cuprate superconductors by exhibiting macroscopic occupation of a quantum state and vanishing viscosity at high temperatures.
Journal ArticleDOI
Towards Bose-Einstein condensation of excitons in potential traps.
TL;DR: Inspired by experiments on atom condensation, and using specially designed semiconductor nanostructures, the photoluminescence measurements show that the quasi-two-dimensional excitons indeed condense at the bottom of the traps, giving rise to a statistically degenerate Bose gas.
Journal ArticleDOI
Control of exciton fluxes in an excitonic integrated circuit.
TL;DR: Control of exciton fluxes in an excitonic integrated circuit is demonstrated, showing the direct coupling of photons to excitons, used as the device-operation medium, and may lead to the development of efficient exciton-based optoelectronic devices.
