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

Recently, we realized the formation of a single quantized vortex in nonresonantly optically
stirred exciton-polariton condensates [I. Gnusov et al., Sci. Adv. 9, eadd1299 (2023) 2375 …

Engineering of the orbital angular momentum (OAM) of light due to interaction with photonic
lattices reveals rich physics and motivates potential applications. We report the experimental …

We report on the experimental realization and characterization of an exciton-polariton qubit
prototype. In our system, a Bose-Einstein condensate of semiconductor exciton-polaritons is …

We take advantage of the polariton bistability in semiconductor microcavities to estimate the
interaction strength between lower exciton-polariton and dark exciton states. We combine …

The Berry curvature provides a powerful tool to unify several branches of science through
their geometrical aspect: topology, energy bands, spin and vector fields. While quantum …

The existence and dynamics of stable quantized vortices is an important subject of quantum
many-body physics. Spin–orbital-angular-momentum coupling (SOAMC), a special type of …

This thesis studies light-matter interactions in strong and weak coupling regimes. In the first
part, we study the formation and propagation of exciton-polariton condensates in different …
