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…
Experimental measurement of the divergent quantum metric of an exceptional point
Qing Liao, Charly Leblanc, Jiahuan Ren +6
The geometry of Hamiltonian's eigenstates is encoded in the quantum geometric tensor (QGT). It contains both the Berry curvature, central to the description of topological matter a…
Analogue time machine in a photonic system
D. D. Solnyshkov, G. Malpuech
Analogue physics has successfully tackled the problems of chromodynamics, event horizons, Big Bang and Universe expansion, and many others. Here, we suggest a photonic model system…
Microcavity polaritons for topological photonics
Dmitry D. Solnyshkov, Guillaume Malpuech, Philippe St-Jean +3
Microcavity polaritons are light-matter quasiparticles that arise from the strong coupling between excitons and photons confined in a semiconductor microcavity. They typically oper…
Realistic estimate of the Covid-19 incidence and mortality rate in France
Guillaume Malpuech, Anne Tournadre, Francois Berry +1
Large scale virological testing of SARS-Cov2 is implemented since May 2020 in France. We assume that the positivity of asymptomatic people not being contact cases (ANBC) is represe…
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…
Quantum metric and wavepackets at exceptional points in non-Hermitian systems
D. D. Solnyshkov, C. Leblanc, L. Bessonart +5
The usual concepts of topological physics, such as the Berry curvature, cannot be applied directly to non-Hermitian systems. We show that another object, the quantum metric, which…
Tuning the Berry curvature in 2D Perovskite
Laura Polimeno, Milena De Giorgi, Giovanni Lerario +14
Topological physics and in particular its connection with artificial gauge fields is a forefront topic in different physical systems, ranging from cold atoms to photonics and more…
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…
Spin-orbit coupling in photonic graphene
Zhaoyang Zhang, Shun Liang, Feng Li +6
We generate experimentally a honeycomb refractive index pattern in an atomic vapor cell using electromagnetically-induced transparency. We study experimentally and theoretically th…
