Conformal-invariance of 2D quantum turbulence in an exciton-polariton fluid of light
Riccardo Panico, Alessandra S. Lanotte, Dimitrios Trypogeorgos +4
The similarities of quantum turbulence with classical hydrodynamics allow quantum fluids to provide essential models of their classical analogue, paving the way for fundamental adv…
Dynamics of a vortex lattice in an expanding polariton quantum fluid
Riccardo Panico, Guido Macorini, Lorenzo Dominici +7
If a quantum fluid is driven with enough angular momentum, at equilibrium the ground state of the system is given by a lattice of quantised vortices whose density is prescribed by…
Directional Goldstone waves in polariton condensates close to equilibrium
Dario Ballarini, Davide Caputo, Galbadrakh Dagvadorj +8
Quantum fluids of light are realized in semiconductor microcavities by exciton-polaritons, solid-state quasi-particles with a light mass and sizeable interactions. Here, we use the…
Josephson vortices in a long Josephson junction formed by phase twist in a polariton superfluid
Davide Caputo, Nataliya Bobrovska, Dario Ballarini +7
Quantum fluids of light are an emerging platform for energy efficient signal processing, ultra-sensitive interferometry and quantum simulators at elevated temperatures. Here we dem…
Self-trapping of exciton-polariton condensates
Dario Ballarini, Igor Chestnov, Davide Caputo +7
The self-trapping of exciton-polariton condensates is demonstrated and explained by the formation of a new polaron-like state. Above the polariton lasing threshold, local variation…
Full-Bloch beams and ultrafast Rabi-rotating vortices
Lorenzo Dominici, David Colas, Antonio Gianfrate +8
Strongly-coupled quantum fields, such as multi-component atomic condensates, optical fields and polaritons, are remarkable systems where the simple dynamics of coupled oscillators…
Interactions and scattering of quantum vortices in a polariton fluid
Lorenzo Dominici, R. Carretero-Gonzalez, Jesus Cuevas-Maraver +9
Quantum vortices, the quantized version of classical vortices, play a prominent role in superfluid and superconductor phase transitions. However, their exploration at a particle le…
Twist of generalized skyrmions and spin vortices in a polariton superfluid
Stefano Donati, Lorenzo Dominici, Galbadrakh Dagvadorj +7
We study the spin vortices and skyrmions coherently imprinted into an exciton-polariton condensate on a planar semiconductor microcavity. We demonstrate that the presence of a pola…
Topological order and equilibrium in a condensate of exciton-polaritons
Davide Caputo, Dario Ballarini, Galbadrakh Dagvadorj +9
We report the observation of the Berezinskii-Kosterlitz-Thouless transition for a 2D gas of exciton-polaritons, and through the joint measurement of the first-order coherence both…
Room-temperature superfluidity in a polariton condensate
Giovanni Lerario, Antonio Fieramosca, Fábio Barachati +8
Superfluidity---the suppression of scattering in a quantum fluid at velocities below a critical value---is one of the most striking manifestations of the collective behaviour typic…
Macroscopic Two-Dimensional Polariton Condensates
Dario Ballarini, Davide Caputo, Carlos Sánchez Muñoz +8
We report a record-size, two-dimensional polariton condensate of a fraction of a millimeter radius free from the presence of an exciton reservoir. This macroscopically occupied sta…
Ultrafast control of Rabi oscillations in a polariton condensate
L. Dominici, D. Colas, S. Donati +10
We report the experimental observation and control of space and time-resolved light-matter Rabi oscillations in a microcavity. Our setup precision and the system coherence are so h…
