We review the current hopes for applications of exciton–polaritons in semiconductor
microcavities. These quasi-particles have become distinguished in recent years for a variety …

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 …

Optical multistability in an optical ring cavity filled with a collection of three-level Λ-type
rubidium atoms has been experimentally demonstrated. The observed multistability is very …

Non-linear interactions in coherent gases are not only at the origin of bright and dark
solitons and superfluids; they also give rise to phenomena such as multistability, which hold …

We theoretically investigated a hybrid absorptive–dispersive optical bistability and
multistability behaviour in a three-level V-type system using a microwave field driving a …

We have experimentally observed optical multistability (OM) in an optical ring cavity
containing three-level Λ-type Doppler-broadened rubidium atoms. The shape of the OM …

The transmission of a pump laser resonant with the lower polariton branch of a
semiconductor microcavity is shown to be highly dependent on the degree of circular …

We study the interaction of a nearly resonant linearly polarized laser beam with a cloud of
cold cesium atoms in a high finesse optical cavity. We show theoretically and experimentally …

Temporal polarization instability is seen as an oscillatory or random variation in time of the
polarization parameters of light interacting with a nonlinear system. Spatial polarization …

Optical bistability is studied for a three-level atomic system in Λ-configuration contained in
an optical ring cavity and the effects of spontaneously generated coherence in the presence …
