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…
Fully Integrated Perovskite Polaritonic Circuits with Tunable Lasing and Nonlinear Amplification
Antonio Fieramosca, Vincenzo Ardizzone, Rosanna Mastria +17
Photonic integrated circuits are emerging as a key technology for compact and energy-efficient optical information processing. Yet, their practical implementation remains limited b…
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…
Quantum fluid dimers of hyperbolic exciton-polariton condensates
Ioannis Georgakilas, Antonio Gianfrate, Dimitrios Trypogeorgos +7
Coupled many-body quantum systems give rise to rich emergent physics and abundance of both stationary and dynamical behaviours. Designing platforms with tunable and distinct forms…
Condensation dynamics in a two-dimensional photonic crystal waveguide
Maria Efthymiou-Tsironi, Antonio Gianfrate, Dimitrios Trypogeorgos +6
Exciton-polariton condensation occurs at the extrema of the underlying dispersion where the density of states diverges and carriers can naturally accumulate. The existence of multi…
