Steady state oscillations of circular currents in concentric polariton condensates
Vladimir Lukoshkin, Evgeny Sedov, Vladimir Kalevich +3
Concentric ring exciton polariton condensates emerging under non-resonant laser pump in an annular trapping potential support persistent circular currents of polaritons. The trappi…
Double ring polariton condensates with polariton vortices
Evgeny Sedov, Vladimir Lukoshkin, Vladimir Kalevich +4
We study formation of superfluid currents of exciton polaritons in annular polariton condensates in a cylindrical micropillar cavity under the spatially localised nonresonant optic…
Superfluid currents in half-moon polariton condensates
E. S. Sedov, V. A. Lukoshkin, V. K. Kalevich +3
We excite exciton-polariton condensates in half-moon shapes by the non-resonant optical excitation of GaAs-based cylindrical pillar microcavities. In this geometry, the π-jump of t…
Persistent circular currents of exciton-polaritons in cylindrical pillar microcavities
V. A. Lukoshkin, V. K. Kalevich, M. M. Afanasiev +5
We have experimentally observed an eddy current of exciton polaritons arising in a cylindrical GaAs/AlGaAs pillar microcavity under the nonresonant optical pumping. The polariton c…
Controllable structuring of exciton-polariton condensates in cylindrical pillar microcavities
V. K. Kalevich, M. M. Afanasiev, V. A. Lukoshkin +7
We observe condensation of exciton polaritons in quantum states composed of concentric rings when exciting cylindrical pillar GaAs/AlGaAs microcavities non-resonantly by a focused…
Ring-shaped polariton lasing in pillar microcavities
V. K. Kalevich, M. M. Afanasiev, V. A. Lukoshkin +4
Optically generated exciton-polaritons in cylindric semiconductor pillar microcavity with embedded GaAs/AlGaAs quantum wells demonstrate a clear polariton lasing regime. When excit…
Phase diagrams of magnetopolariton gases
V. P. Kochereshko, M. V. Durnev, L. Besombes +17
The magnetic field effect on phase transitions in electrically neutral bosonic systems is much less studied than those in fermionic systems, such as superconducting or ferromagneti…
Spin-induced optical second harmonic generation in the centrosymmetric magnetic semiconductors EuTe and EuSe
B. Kaminski, M. Lafrentz, R. V. Pisarev +9
Spectroscopy of the centrosymmetric magnetic semiconductors EuTe and EuSe reveals spin-induced optical second harmonic generation (SHG) in the band gap vicinity at 2.1-2.4eV. The m…
