Optical self-cooling of a membrane oscillator in a cavity optomechanical experiment at room temperature
P. Vezio, M. Bonaldi, A. Borrielli +5
Thermal noise is a major obstacle to observing quantum behavior in macroscopic systems. To mitigate its effect, quantum optomechanical experiments are typically performed in a cryo…
Spectral Analysis of Quantum Field Fluctuations in a Strongly Coupled Optomechanical System
A. Ranfagni, F. Marino, F. Marin
With a levitodynamics experiment in the strong and coherent quantum optomechanical coupling regime, we demonstrate that the oscillator acts as a broadband quantum spectrum analyzer…
Intermittent chaotic spiking in the van der Pol-FitzHugh-Nagumo system with inertia
Marzena Ciszak, Salvador Balle, Oreste Piro +1
The three-dimensional (3D) Fitzhugh-Nagumo neuron model with inertia was shown to exhibit a chaotic mixed-mode dynamics composed of large-amplitude spikes separated by an irregular…
Collective excitability in highly diluted networks of rotators
Gabriele Paolini, Marzena Ciszak, Francesco Marino +2
We report on collective excitable events in a highly-diluted random network of non-excitable nodes. Excitability arises thanks to a self-sustained local adaptation mechanism that d…
Two-dimensional quantum motion of a levitated nanosphere
A. Ranfagni, K. Børkje, F. Marino +1
We report on the two-dimensional (2D) dynamics of a levitated nanoparticle in an optical cavity. The motion of the nanosphere is strongly coupled to the cavity field by coherent sc…
Collective canard explosions of globally-coupled rotators with adaptive coupling
Marzena Ciszak, Simona Olmi, Giacomo Innocenti +2
Canards, special trajectories that follow invariant repelling slow manifolds for long time intervals, have been frequently observed in slow-fast systems of either biological, chemi…
