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…
Coherence of a non-equilibrium polariton condensate across the interaction-mediated phase transition
P. Comaron, E. Estrecho, M. Wurdack +9
The emergence of spatial coherence in a confined two-dimensional Bose gas of exciton-polaritons with tuneable interactions offers a unique opportunity to explore the role of intera…
Dynamics of Onsager vortex clustering in decaying turbulent polariton quantum fluids
P. Comaron, R. Panico, D. Ballarini +1
We investigate the turbulent properties of a confined driven-dissipative polariton quantum fluid after a pulsed excitation. Using numerical simulations, we provide insight into the…
