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 …

Integrated switching devices comprise the building blocks of ultrafast optical signal
processing,. As the next stage following intensity switching,,, circular polarization switches …

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 …

We present a practical scheme for creating topological polaritons in garden-variety systems
based, for example, on zinc-blende semiconductor quantum wells. Our proposal requires a …

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 …

All-inorganic metal halides perovskites (CsPbX3, X= Br or Cl) show strong excitonic and
spin-orbital coupling effects, underpinning spin-selective excitonic transitions and therefore …

The impact of a highly charged ion onto a solid gives rise to charge exchange between the
ion and target atoms, so that a slow ion gets neutralized in the vicinity of the surface. Using …
