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…
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…
Quantum impurities in finite-temperature Bose gases: Detecting vortex proliferation across the BKT and BEC transitions
Paolo Comaron, Nathan Goldman, Atac Imamoglu +1
Detecting vortices in neutral superfluids represents an outstanding experimental challenge. Using stochastic classical-field methods, we theoretically show that a quantum impurity…
Multicomponent Kardar-Parisi-Zhang Universality in Degenerate Coupled Condensates
Harvey Weinberger, Paolo Comaron, Marzena H. SzymaÅska
We show that the multicomponent Kardar-Parisi-Zhang equation describes the low-energy theory for phase fluctuations in a degenerate non-equilibrium driven-dissipat…
