Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

Photoluminescence and reflectivity spectra of a high-quality InGaAs/GaAs quantum well
structure reveal a series of ultranarrow peaks attributed to the quantum confined exciton …

The precise adjustment of the polariton condensate flow under incoherent excitation
conditions is an indispensable prerequisite for polariton-based logic gate operations. In this …

Polaritons are quasiparticles arising from the strong coupling of electromagnetic waves in
cavities and dipolar oscillations in a material medium. In this framework, localized surface …

Phase fluctuations determine the low-energy properties of quantum condensates. However,
at the condensation threshold, both density and phase fluctuations are relevant. While …

We report the observation of coherent oscillations in the relaxation dynamics of an exciton–
polariton condensate that were driven by parametric scattering processes. As a result of the …

Whispering gallery modes in a microwire are characterized by a nearly equidistant energy
spectrum. In the strong exciton–photon coupling regime, this system represents a bosonic …

We report on the experimental evidence for a nanosecond timescale spin memory based on
nonradiative excitons with large in-plane wave vector. The effect manifests itself in magnetic …

We present a stability analysis on a driven-dissipative electron-hole condensate in the BCS
(Bardeen-Cooper-Schrieffer)–BEC (Bose-Einstein condensation) crossover region …

We propose a physical mechanism which enables permanent Rabi oscillations in driven-
dissipative condensates of exciton-polaritons in semiconductor microcavities subjected to …
