Deterministic Vortex Generation from Coupled Trapped Polariton Condensate Triad
X. Qin, N. Pitanios, S. Dam +4
We present the deterministic generation and all-optical switching of ternary topologically distinct vortex states in a triad of trapped exciton-polariton condensates with direct st…
Subcritical bifurcation and on-off bistability in ballistic polariton condensates
Oleg I. Utesov, Soohong Choi, Pavel Kozhevin +11
Dynamics of exciton-polariton condensates under continuous-wave incoherent Gaussian optical pumping is considered. It is shown that the conventional supercritical Stuart-Landau pic…
Localization--non-ergodic transition in controllable-dimension fractal networks from diffusion-limited aggregation
Oleg I. Utesov, Alexei Andreanov, Tomasz Bednarek +2
Our study connects the physics of disordered integer-dimensional systems and regular self-similar objects by studying spectral properties of fractal agglomerates with tunable dimen…

We demonstrate the formation of a high angular momentum turbulent state in an exciton-polariton quantum fluid with TE-TM Spin-Orbit Coupling (SOC). The transfer of particles from q…
Parametric amplification of topological interface states in synthetic Andreev bands
Ismael Septembre, Sergei Koniakhin, Julia Meyer +2
A driven-dissipative nonlinear photonic system (e.g. exciton-polaritons) can operate in a gapped superfluid regime. We theoretically demonstrate that the reflection of a linear wav…
Taming the snake instabilities in a polariton superfluid
Ferdinand Claude, Sergei V. Koniakhin, Anne Maître +8
The dark solitons observed in a large variety of nonlinear media are unstable against the modulational (snake) instabilities and can break in vortex streets. This behavior has been…
Parallel dark soliton pair in a bistable 2D exciton-polariton superfluid
Giovanni Lerario, Sergei V. Koniakhin, Anne Maître +7
Collective excitations, such as vortex-antivortex and dark solitons, are among the most fascinating effects of macroscopic quantum states. However, 2D dark solitons are unstable an…
2D Quantum Turbulence in Polariton Condensates
S. V. Koniakhin, O. Bleu, G. Malpuech +1
The coexistence of the energy and enstrophy cascades in 2D quantum turbulence is one of the important open questions in the studies of quantum fluids. Here, we show that polariton…
