Topological turbulence in spin-orbit-coupled driven-dissipative quantum fluids of light generates high angular momentum states
S. V. Koniakhin, G. Malpuech, D. D. Solnyshkov +1
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…
Analog Kerr Black hole and Penrose effect in a Bose-Einstein Condensate
D. D. Solnyshkov, C. Leblanc, S. V. Koniakhin +2
Analog physics allows simulating inaccessible objects, such as black holes, in the lab. We propose to implement an acoustic Kerr black hole with quantized angular momentum in a pol…
