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…
Universality beyond the Kibble-Zurek mechanism in the condensation of coherently coupled Bose gases
Subhadeep Patra, Paolo Comaron, Arko Roy
We study the universal spatial statistics of point-like topological defects formed during the nonequilibrium condensation of a coherently coupled Bose gas using the stochastic proj…
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…
Temporal hopping dynamics in exciton-polariton condensation
Elena Rozas, Wojciech Bukalski, Yannik Brune +9
Polariton condensates provide a versatile platform for exploring non-equilibrium phase transitions and collective phenomena in open quantum systems. Near the condensation threshold…
Persistent, controllable circulation of a polariton ring condensate
Q. Yao, P. Comaron, H. A. Alnatah +7
Persistent circulation is a canonical effect of superfluidity. In previous experiments, quantized circulation has been observed in polariton condensates, usually far from equilibri…
Directional optical parametric amplification in a hyperbolic metamaterial
Antonio Gianfrate, Dimitrios Trypogeorgos, Paolo Comaron +5
Optical parametric amplification (OPA) comprises essentially a nonlinear four-wave mixing process in which a "pump" and a "signal" field give rise to an "idler" field under certain…
