Interest in the multiple facets of optical vortices has flourished in the last three decades. This
review examines the basic research and applications of the interplay between optical …

The appearance of quantized vortices in the classical “rotating bucket” experiments of liquid
helium and ultracold dilute gases provides the means for fundamental and comparative …

Microcavity exciton‐polaritons are attractive quantum quasi‐particles resulting from strong
light–matter coupling in a quantum‐well‐cavity structure. They have become one of the most …

Exciton–polaritons in a microcavity are composite two-dimensional bosonic quasiparticles,
arising from the strong coupling between confined light modes in a resonant planar optical …

Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor)
provide a solid-state platform for studies of nonequilibrium quantum systems with a …

We report on the observation of half-quantum vortices (HQVs) in the easy-plane polar phase
of an antiferromagnetic spinor Bose-Einstein condensate. Using in situ magnetization …

The rotational response of quantum condensed fluids is strikingly distinct from rotating
classical fluids, especially notable for the excitation and ordering of quantized vortex …

We report on the experimental realization and characterization of a qubit analog with
semiconductor exciton-polaritons. In our system, a polaritonic condensate is confined by a …

Superposition states of circular currents of exciton-polaritons mimic the superconducting flux
qubits. The phase of a polariton fluid must change by an integer number of 2 π when going …

We study the spin vortices and skyrmions coherently imprinted into an exciton–polariton
condensate on a planar semiconductor microcavity. We demonstrate that the presence of a …
