Generation and dynamics of vortex lattices in coherent exciton-polariton fields.
نویسندگان
چکیده
Vortex dynamics in coherent ensembles of exciton polaritons (condensates) is studied in the framework of the polarization-dependent Gross-Pitaevskii equation. Vortex lattices can be resonantly excited in the polariton field by the interference of three or more optical pumps. Vortex-antivortex pairs can also appear in polariton condensates due to scattering with disorder. The nonlinear vortex dynamics is characterized by interactions of vortex cores and vortex-antivortex recombination.

Coherent and incoherent aspects of polariton dynamics in semiconductor microcavities
The interaction between coherent polaritons and incoherent excitons plays an important role in polariton physics. Using resonant pump-probe spectroscopy with selective excitation of single polariton branches, we investigate the different dephasing mechanisms responsible for generating a long-lived exciton reservoir. As expected, pumping the upper polariton results in a strong dephasing process ...
متن کاملElectrically tunable artificial gauge potential for polaritons
Neutral particles subject to artificial gauge potentials can behave as charged particles in magnetic fields. This fascinating premise has led to demonstrations of one-way waveguides, topologically protected edge states and Landau levels for photons. In ultracold neutral atoms, effective gauge fields have allowed the emulation of matter under strong magnetic fields leading to realization of Harp...
متن کاملUltrafast Polariton-Phonon Dynamics of Strongly Coupled Quantum Dot-Nanocavity Systems
We investigate the influence of exciton-phonon coupling on the dynamics of a strongly coupled quantum dot-photonic crystal cavity system and explore the effects of this interaction on different schemes for nonclassical light generation. By performing time-resolved measurements, we map out the detuningdependent polariton lifetime and extract the spectrum of the polariton-to-phonon coupling with ...
متن کاملTerahertz Sideband Generation and Coherent Control in Semiconductor Microcavities
The controlled variation of the temperature, magnetic field, electrical bias, and quantum-well (QW) thickness [1] have all been employed to afford tunability of the exciton–cavity-photon coupling in semiconductor microcavities (MC’s). Time-dependent knobs, however, have attracted scant attention. As we show in this Letter, the modulation of the optical properties of a MC at THz frequencies may ...
متن کاملFrequency combs with weakly lasing exciton-polariton condensates.
We predict the spontaneous modulated emission from a pair of exciton-polariton condensates due to coherent (Josephson) and dissipative coupling. We show that strong polariton-polariton interaction generates complex dynamics in the weak-lasing domain way beyond Hopf bifurcations. As a result, the exciton-polariton condensates exhibit self-induced oscillations and emit an equidistant frequency co...
