Dimensional reduction for optical beams with thermal nonlocal nonlinearity
Francesco Lorenzi, Luca Salasnich
Nonlocal optical nonlinearities arising from the thermorefractive effect provide a long-range material response determined by heat diffusion and absorption. In graded-index media,…
Bosonic Josephson junction dynamics: interplay between quantum and thermal fluctuations
Andrea Bardin, Francesco Lorenzi, Luca Salasnich
We investigate the superfluid dynamics of a Josephson junction beyond the mean-field description, incorporating the role of thermal fluctuations as well as quantum fluctuations. Us…
Variational treatment of the electromagnetic field in an optical cavity with a moving mirror
Francesco Lorenzi, Maria Guglielmina Pelizzo, Luca Salasnich
Optical cavities with moving mirrors provide a versatile platform for exploring radiation-matter interactions and optically mediated mechanical effects, whose control has wide tech…
Experimental Observation of Single- and Multisite Matter-Wave Solitons in an Optical Accordion Lattice
Robbie Cruickshank, Francesco Lorenzi, Arthur La Rooij +5
We report the experimental observation of discrete bright matter-wave solitons with attractive interaction in an optical lattice. Using an accordion lattice with adjustable spacing…
Optical Cavity in Relativistic Regime for Laser Propulsion
Francesco Lorenzi, Luca Salasnich, Maria Guglielmina Pelizzo
Laser propulsion has been proposed for relativistic interstellar flights, but it faces the significant challenge of requiring extremely powerful laser radiation due to the inherent…
Low-energy atomic scattering: s-wave relation between the interaction potential and the phase shift
Francesco Lorenzi, Luca Salasnich
We investigate the on-shell approximation in the context of s-wave scattering for ultracold two-body collisions. Our analysis systematically covers spatial dimensions D=1,2,3 , wit…
