Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

Microcavity polaritons are light-matter quasiparticles that arise from the strong coupling
between excitons and photons confined in a semiconductor microcavity. They are typically …

Conventional semiconductor laser emission relies on stimulated emission of photons,, which
sets stringent requirements on the minimum amount of energy necessary for its operation,. In …

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 …

We demonstrate experimentally the condensation of exciton polaritons through optical
trap**. The nonresonant pump profile is shaped into a ring and projected to a high quality …

We report on the experimental observation of the nonlinear analogue of the optical spin Hall
effect under highly nonresonant circularly polarized excitation of an exciton-polariton …

The topological spin-Hall effect causes different spins to propagate in opposite directions
based on Hermitian physics. The non-Hermitian skin effect causes the localization of a large …

Modulational instabilities play a key role in a wide range of nonlinear optical phenomena,
leading, eg, to the formation of spatial and temporal solitons, rogue waves, and chaotic …

We investigate the phase coupling between spatially separated polariton condensates
under nonresonant optical pulsed excitation. In the simple case of two condensates, we …

Recent experiments showed the transfer of orbital angular momentum (OAM) from a
nonresonant laser onto an exciton-polariton condensate, despite earlier views that the …
