Emission of time-ordered photon pairs from a coherently-driven Kerr microcavity
Ferdinand Claude, Yueguang Zhou, Sylvain Ravets +8
Weakly-interacting many-body systems possess remarkable quantum properties that are essential components of quantum technologies, and constitute a topic of fundamental interest. He…
Excitonic oscillator-strength saturation dominates polariton-polariton interactions
Maxime Richard, Irénée Frérot, Sylvain Ravets +8
Exciton-polaritons in semiconductor microcavities exhibit large two-body interactions that, thanks to ever refined nanotechnology techniques, are getting closer and closer to the q…
Observation of the diffusive Nambu-Goldstone mode of a non-equilibrium phase transition
Ferdinand Claude, Maxime J. Jacquet, Michiel Wouters +4
Second-order phase transitions are governed by spontaneous symmetry breaking, which yield collective excitations with a gapless spectrum called Nambu-Goldstone (NG) modes. While NG…
Spectrum of collective excitations of a quantum fluid of polaritons
Ferdinand Claude, Maxime J. Jacquet, Iacopo Carusotto +3
We use a recently developed high-resolution coherent probe spectroscopy method to investigate the dispersion of collective excitations of a polaritonic quantum fluid. We measure th…
Analogue quantum simulation of the Hawking effect in a polariton superfluid
Maxime J. Jacquet, Malo Joly, Luca Giacomelli +5
Quantum effects of fields on curved spacetimes may be studied in the laboratory thanks to quantum fluids. Here we use a polariton fluid to study the Hawking effect, the correlated…
High-resolution coherent probe spectroscopy of a polariton quantum fluid
Ferdinand Claude, Maxime J Jacquet, Romain Usciati +4
Characterising elementary excitations in quantum fluids is essential to study collective effects within. We present an original angle-resolved coherent probe spectroscopy technique…
Quantum vacuum excitation of a quasi-normal mode in an analog model of black hole spacetime
Maxime J Jacquet, Luca Giacomelli, Quentin Valnais +6
Vacuum quantum fluctuations near horizons are known to yield correlated emission by the Hawking effect. We use a driven-dissipative quantum fluid of microcavity polaritons as an an…
Dissipative phase transition with driving-controlled spatial dimension and diffusive boundary conditions
Z. Li, F. Claude, T. Boulier +4
We investigate theoretically and experimentally a first-order dissipative phase transition, with diffusive boundary conditions and the ability to tune the spatial dimension of the…
Spontaneous generation, enhanced propagation and optical imprinting of quantized vortices and dark solitons in a polariton superfluid: towards the control of quantum turbulence
Anne Maitre, Ferdinand Claude, Giovani Lerario +7
In resonantly pumped polariton superfluids we recently explored a new regime based on the bistability of the polariton system to enhance the propagation of polariton fluids up to m…
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…
Microcavity Polaritons for Quantum simulation
Thomas Boulier, Maxime J. Jacquet, Anne Maître +8
Quantum simulations are one of the pillars of quantum technologies. These simulations provide insight in fields as varied as high energy physics, many-body physics, or cosmology to…
Dark-soliton molecules in an exciton-polariton superfluid
Anne Maître, Giovanni Lerario, Adrià Medeiros +5
The general theory of dark solitons relies on repulsive interactions and therefore predicts the impossibility to form dark-soliton bound states. One important exception to this pre…
Stationary quantum vortex street in a driven-dissipative quantum fluid of light
S. V. Koniakhin, O. Bleu, D. D. Stupin +8
We investigate the formation of a new class of density-phase defects in a resonantly driven 2D quantum fluid of light. The system bistability allows the formation of low density re…
Topological transformations of speckles
Jerome Gateau, Ferdinand Claude, Gilles Tessier +1
Deterministic control of coherent random light is highly important for information transmission through complex media. However, only a few simple speckle transformations can be ach…
