Exciton-polaritons in semiconductor microcavities have become a model system for the
studies of dynamical Bose–Einstein condensation, macroscopic coherence, many-body …

We use coupled micropillars etched out of a semiconductor microcavity to engineer a spin-
orbit Hamiltonian for photons and polaritons in a microstructure. The coupling between the …

Microcavity polaritons are mixed light–matter quasiparticles with extraordinary nonlinear
properties, which can be easily accessed in photoluminescence experiments. Thanks to the …

Exciton polariton condensation is a macroscopic quantum state that can be efficiently
controlled by an external field through a nonlinear interaction. In an annular potential …

Polariton condensates are macroscopic quantum states formed by half-matter half-light
quasiparticles, thus connecting the phenomena of atomic Bose–Einstein condensation …

We investigate non-Hermitian skin modes in laser arrays with spatially localized excitation.
Intriguingly, we observe an unusual threshold behavior when selectively pum** either the …

We study the dynamics of exciton-polariton condensates in reconfigurable potentials created
by an incoherent optical pump. The mode selection in the effective optically induced trap is …

Topological flat bands are increasingly recognized as an important paradigm to study the
effects of quantum geometry and topology in strongly correlated systems. The recently …

We demonstrate that due to strong modal interactions through cross-gain saturation, the
onset of a new lasing mode can switch off an existing mode via a negative power slope. In …

Using the correspondence between (saturated) nonlinear and (unsaturated) linear dielectric
constants, we propose a simple and systematic method to achieve selective excitation of …
