Dissipation-enhanced vortex clustering in a compressible quantum fluid
P. Comaron, M. Matuszewski, D. Sanvitto +2
Vortex clustering is commonly associated with conservative two-dimensional quantum-fluid dynamics. Therefore, particle loss is mainly expected to limit clustering by shortening the…
Magnetic-field driven hybridization of heavy- and light-hole Rydberg excitons in GaAs quantum wells
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
We present a combined theoretical and experimental study of ground and excited Rydberg exciton states in wide GaAs quantum wells exposed to a magnetic field in the Faraday geometry…
Very strong light-matter coupling in patterned GaAs heterostructures
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
The very strong light-matter coupling regime enables the non-perturbative modification of matter properties via light. Using a patterned GaAs/AlGaAs waveguide with twelve wide quan…
Exciton-Tunable Phase Control and Superstrong Coupling Through Multimode Polariton Engineering in Planar Waveguides
Johannes Bürger, Erika Cortese, Simone Di Muzio +3
Strong light-matter coupling in optical waveguides provides a versatile platform for engineering hybrid polaritonic modes and their dispersion. Here we investigate multimode excito…
Pulse, polarization and topology shaping of polariton fuids
Lorenzo Dominici, David Colas, Stefano Donati +9
Here we present different approaches to ultrafast pulse and polarization shaping, based on a ``quantum fluid'' platform of polaritons. Indeed we exploit the normal modes of two dim…
Dynamical universality in a driven quantum fluid of light
Ivan Gnusov, Paolo Comaron, Antonio Gianfrate +6
Universal scaling near phase transitions is one of the central ideas of physics, linking the growth of spatial correlations to the slowing down of dynamics. So far, direct experime…
