We analyze nonequilibrium phase transitions in microcavity polariton condensates trapped in optically induced annular potentials. We develop an analytic model for annular optical traps, which gives an intuitive interpretation for recent experimental observations on the polariton spatial mode switching with variation of the trap size. In the vicinity of polariton lasing threshold we then develop a nonlinear mean-field model accounting for interactions and gain saturation, and identify several… Expand

Abstract In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic phenomena and systems as they appear in the literature on quantum materials and quantum optics.Expand
Geometric frustration in polygons of polariton condensates creating vortices of varying topological charge
Polariton condensates stand out from other superfluid systems due to their particularly strong interparticle interactions combined with their non-equilibrium nature, and as such provide an alternative testbed for the study of vortices. Expand

Dissipative Kerr solitons arising from parametric gain in ring microresonators are usually described within a classical mean-field framework. Here, we develop a quantum-mechanical model ofExpand

We study an emergent semiclassical time crystal composed of two interacting driven-dissipative bosonic modes. The system has a discrete $\mathbb Z_2$ spatial symmetry which, depending on the strengthExpand


Polariton condensation in an optically induced two-dimensional potential
We demonstrate experimentally the condensation of exciton polaritons through optical trapping. The nonresonant pump profile is shaped into a ring and projected to a high quality factor microcavityExpand
Optical superfluid phase transitions and trapping of polariton condensates.
This work directly image persistently circulating superfluid and shows how flows of light-matter quasiparticles are dominated by the quantum pressure in such configurable laser-written potential landscapes. Expand
Bose-Einstein Condensation of Microcavity Polaritons in a Trap
Polaritons are created in a harmonic potential trap analogous to atoms in optical traps and observe a number of signatures of Bose-Einstein condensation: spectral and spatial narrowing, a peak at zero momentum in the momentum distribution, first-order coherence, and spontaneous linear polarization of the light emission.

Real-space collapse of a polariton condensate
The unique phenomenology that is observed when a pulse of light impacts the polariton vacuum is reported: the fluid which is suddenly created does not splash but instead coheres into a very bright spot, suggesting that an unconventional mechanism is at play. Expand
Frequency combs with weakly lasing exciton-polariton condensates.
It is shown that strong polariton-polariton interaction generates complex dynamics in the weak-lasing domain way beyond Hopf bifurcations and exhibit self-induced oscillations and emit an equidistant frequency comb light spectrum. Expand
Radiative coupling and weak lasing of exciton-polariton condensates
In spite of having finite life-time exciton-polaritons in microcavities are known to condense at strong enough pumping of the reservoir. We present an analytical theory of such Bose-condensates on aExpand
Nonresonant optical control of a spinor polariton condensate

Coupled counterrotating polariton condensates in optically defined annular potentials
The ability to precisely control the structure of the petal condensates both by carefully modifying the excitation geometry as well as perturbing the system on ultrafast timescales to reveal unexpected superfluid dynamics is demonstrated. Expand

Single-shot condensation of exciton polaritons and the hole burning effect
The role of the spatial hole burning in condensation of long‐lived exciton polaritons is demonstrated by imaging the condensates in a single-shot excitation regime and it is demonstrated that condensation is strongly influenced by an incoherent reservoir. Expand
