From a theoretical point of view, we discuss a variety of phenomena linked to the spin and
polarization degree of freedom of exciton-polaritons in semiconductor microcavities. We start …

Semiconductor microcavities, in which strong coupling of excitons to confined photon modes
leads to the formation of exciton–polariton modes, have increasingly become a focus for the …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

A remarkable analogy is established between the well-known spin Hall effect and the
polarization dependence of Rayleigh scattering of light in microcavities. This dependence …

Coherent manipulation of spin ensembles is a key issue in the development of spintronics.
In particular, multivalued spin switching may lead to new schemes of logic gating and …

By exploiting the polarization multistability of polaritons, we show that polarized signals can
be conducted in the plane of a semiconductor microcavity along controlled channels or …

New effects of polarization multistability and polarization hysteresis in a coherently driven
polariton system in a semiconductor microcavity are predicted and theoretically analyzed …

We observe a spontaneous parity breaking bifurcation to a ferromagnetic state in a spatially
trapped exciton-polariton condensate. At a critical bifurcation density under nonresonant …

Although exciton–polariton lasers have been experimentally demonstrated in a variety of
material systems, robust practical implementations are still challenging. Similarities with …

We use the truncated Wigner approximation to derive stochastic classical field equations for
the description of polariton condensates. Our equations are shown to reduce to the …
