Dispersion relation of the collective excitations in a resonantly driven polariton fluid
Petr Stepanov, Ivan Amelio, Jean-Guy Rousset +6
Exciton-polaritons in semiconductor microcavities constitute the archetypal realization of a quantum fluid of light. Under coherent optical drive, remarkable effects such as superf…
Slow diffusion and long lifetime in metal halide perovskites for photovoltaics
Adrien Bercegol, F. Javier Ramos, Amelle Rebai +4
Metal halide perovskites feature excellent absorption, emission and charge carrier transport properties. These materials are therefore very well suited for photovoltaics applicatio…
Giant spin Meissner effect in a non-equilibrium exciton-polariton gas
M. Król, R. Mirek, D. Stephan +7
The suppression of Zeeman energy splitting due to spin-dependent interactions within a Bose-Einstein condensate (the spin Meissner effect) was predicted to occur up to a certain va…
Spin polarized semimagnetic exciton-polariton condensate in magnetic field
Mateusz Król, Rafał Mirek, Katarzyna Lekenta +7
Owing to their integer spin, exciton-polaritons in microcavities can be used for observation of non-equilibrium Bose-Einstein condensation in solid state. However, spin-related phe…
Effect of magnetic field on the lasing threshold of a semimagnetic polariton condensate
J. -G. Rousset, B. Piętka, M. Król +5
We evidence magnetic field triggered polariton lasing in a microcavity containing semimagnetic quantum wells. This effect is associated with a decrease of the polariton lasing thre…

Angular dependence of giant Zeeman effect for semi-magnetic cavity polaritons
R. Mirek, M. Król, K. Lekenta +7
The observation of spin-related phenomena of microcavity polaritons has been limited due to weak Zeeman effect of non-magnetic semiconductors. We demonstrate that the incorporation…
Comparison of magneto-optical properties of various excitonic complexes in CdTe and CdSe self-assembled quantum dots
