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…
Geometric control of hyperbolic exciton-polariton condensate dimers
Ioannis Georgakilas, Antonio Gianfrate, Dimitrios Trypogeorgos +7
Coupled many-body quantum systems exhibit rich emergent physics with diverse stationary and dynamical behaviors. By engineering platforms with tunable and distinct coupling mechani…
Emerging supersolidity from a polariton condensate in a photonic crystal waveguide
Dimitrios Trypogeorgos, Antonio Gianfrate, Manuele Landini +10
A supersolid is a counter-intuitive phase of matter where its constituent particles are arranged into a crystalline structure, yet they are free to flow without friction. This requ…
Bose-Einstein Condensation in Gap-Confined Exciton-Polariton States
F. Riminucci, A. Gianfrate, D. Nigro +9
The development of patterned multi-quantum well heterostructures in GaAs/AlGaAs waveguides has recently allowed to achieve exciton-polariton condensation in a topologically protect…
Reconfigurable quantum fluid molecules of bound states in the continuum
Antonio Gianfrate, Helgi Sigurdsson, Vincenzo Ardizzone +10
Topological bound states in the continuum are confined wave-mechanical objects that offer advantageous ways to enhance light-matter interactions in compact photonic devices. In par…
Fabrication of Nanostructured GaAs/AlGaAs Waveguide for Low-Density Polariton Condensation from a Bound State in the Continuum
F. Riminucci, V. Ardizzone, L. Francaviglia +13
Exciton-polaritons are hybrid light-matter states that arise from strong coupling between an exciton resonance and a photonic cavity mode. As bosonic excitations, they can undergo…
Ultrafast, low-energy, all-optical switch in polariton waveguides
D. G. Suárez-Forero, F. Riminucci, V. Ardizzone +8
The requirement for optical-electrical-optical conversion of signals in optical technologies is often one of the majors bottleneck in terms of speed and energy consumption. The use…
Polariton Bose-Einstein condensate from a Bound State in the Continuum
V. Ardizzone, F. Riminucci, S. Zanotti +13
Optical bound states in the continuum (BIC) are peculiar topological states that, when realized in a planar photonic crystal lattice, are symmetry-protected from radiating in the f…
Demonstration of dipolar-induced enhancement of parametric effects in polariton waveguides
Daniel G. Suárez-Forero, Fabrizio Riminucci, Vincenzo Ardizzone +13
Exciton-polaritons are hybrid light-matter excitations arising from the non-perturbative coupling of a photonic mode and an excitonic resonance. Behaving as interacting photons, th…
Electrically controlled waveguide polariton laser
D. G. Suárez-Forero, F. Riminucci, V. Ardizzone +8
Exciton-polaritons are mixed light-matter particles offering a versatile solid state platform to study many-body physical effects. In this work we demonstrate an electrically contr…
Plasmonic lenses for tunable ultrafast electron emitters at the nanoscale
Daniel B. Durham, Fabrizio Riminucci, Filippo Ciabattini +4
Simultaneous spatio-temporal confinement of energetic electron pulses to femtosecond and nanometer scales is a topic of great interest in the scientific community, given the potent…
