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…
Polariton fluids for analogue gravity physics
M. J. Jacquet, T. Boulier, F. Claude +8
Analogue gravity enables the study of fields on curved spacetimes in the laboratory. There are numerous experimental platforms in which amplification at the event horizon or the er…
Dispersion relation of the collective excitations in a resonantly driven polariton fluid
Petr Stepanov, Ivan Amelio, Jean-Guy Rousset +6
Exciton-polaritons in semiconductor microcavities constitute the archetypal realization of a quantum fluid of light. Under coherent optical drive, remarkable effects such as superf…
Theoretical study of stimulated and spontaneous Hawking effects from an acoustic black hole in a hydrodynamically flowing fluid of light
Pjotrs Grisins, Hai Son Nguyen, Jacqueline Bloch +2
We propose an experiment to detect and characterize the analog Hawking radiation in an analog model of gravity consisting of a flowing exciton-polariton condensate. Under a suitabl…
Stochastic precession of the polarization in a polariton laser
Vera Giulia Sala, Félix Marsault, Michiel Wouters +5
Microcavity polaritons in the lasing regime undergo a spontaneous symmetry breaking transition resulting in coherent emission with a well defined polarization. The order parameter…
Fractal energy spectrum of a polariton gas in a Fibonacci quasi-periodic potential
Dimitrii Tanese, Evgeni Gurevich, Florent Baboux +7
We report on the study of a polariton gas confined in a quasi-periodic one dimensional cavity, described by a Fibonacci sequence. Imaging the polariton modes both in real and recip…
Direct observation of Dirac cones and a flatband in a honeycomb lattice for polaritons
Thibaut Jacqmin, Iacopo Carusotto, Isabelle Sagnes +7
Two-dimensional lattices of coupled micropillars etched in a planar semiconductor microcavity offer a workbench to engineer the band structure of polaritons. We report experimental…
Propagation and amplification dynamics of 1D polariton condensates
E. Wertz, A. Amo, D. D. Solnyshkov +9
The dynamics of propagating polariton condensates in one-dimensional microcavities is investigated through time resolved experiments. We find a strong increase in the condensate in…
Half-solitons in a polariton quantum fluid behave like magnetic monopoles
R. Hivet, H. Flayac, D. D. Solnyshkov +8
Monopoles are magnetic charges, point-like sources of magnetic field. Contrary to electric charges they are absent in Maxwell's equations and have never been observed as fundamenta…
