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 …

The coupling of two macroscopic quantum states through a tunnel barrier gives rise to
Josephson phenomena such as Rabi oscillations, the ac and dc effects, or macroscopic self …

Singly quantized vortices have already been observed in many systems, including the
superfluid helium, Bose-Einstein condensates of dilute atomic gases, and condensates of …

Fluids of exciton polaritons, excitations of two-dimensional quantum wells in optical cavities,
show collective phenomena akin to Bose condensation. However, a fundamental difference …

Spin-orbit coupling (SOC) is responsible for a range of spintronic and topological processes
in condensed matter. Here, we show photonic analogs of SOCs in exciton-polaritons and …

Resonant transmission of light through a microcavity in the strong coupling regime is used to
estimate the strength of the interaction between polaritons with parallel (α 1) or antiparallel …

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 …

Practical challenges to extrapolating Moore's law favour alternatives to electrons as
information carriers. Two promising candidates are spin-based and all-optical architectures …

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 …
