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…
Magnetic control of polariton spin transport
Davide Caputo, Evgeny Sedov, Dario Ballarini +3
We show the full control of the polarization dynamics of a propagating exciton-polariton condensate in a planar microcavity by using a magnetic field applied in the Voigt geometry.…
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…
