Jones-Roberts solitary waves and the onset of rotation in a spherical surface condensate
Noel Cuadra, Alberto Villois, Thomas Gasenzer +1
The nonlinear excitations underlying the onset of rotation in a dilute Bose-Einstein condensate confined to a thin spherical shell are studied. These excitations correspond to soli…
Pseudovorticity of 2+1D optical solitons
Ludovica Falsi, Giuseppe Agostino, Alberto Villois +6
In the hydrodynamic representation of a quantum fluid or optical field, vorticity vanishes wherever the phase is well defined, and is instead localized at phase singularities, or q…
Vortex to Rotons Transition in Dipolar Bose-Einstein Condensates
Alberto Villois, Miguel Onorato, Davide Proment
Recent experimental advancements enabled the creation of various systems exhibiting superfluid behavior, with one notable achievement being the development of dipolar Bose-Einstein…
Anomalous correlators, negative frequencies and non-phase-invariant Hamiltonians in random waves
Alberto Villois, Giovanni Dematteis, Yuri V. Lvov +2
We investigate a generic non-phase invariant Hamiltonian model that governs the dynamics of nonlinear dispersive waves. We give evidence that initial data characterized by random p…
Evidence of 1+1D photorefractive stripe solitons deep in the Kerr limit
Ludovica Falsi, Alberto Villois, Francesco Coppini +3
The Kerr nonlinearity allows for exact analytic soliton solutions in 1+1D. While nothing excludes that these solitons form in naturally-occurring real-world 3D settings as solitary…
