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…
Wave Attenuation in Drifting Sea Ice: A Mechanistic Model for Observed Decay Profiles
Rhys Ransome, Davide Proment, Ian A. Renfrew +1
Wave-sea ice interactions shape the transition zone between open ocean and pack ice in the polar regions. Most theoretical paradigms, implemented in coupled wave-sea ice models, pr…
The effect of discrete-time evolution on thermalisation in a lattice
Thomas Moorcroft, Alberto Amo, François Copie +3
Particles subject to weak contact interactions in a finite-size lattice tend to thermalise. The Hamiltonian evolution ensures energy conservation and the final temperature is fully…
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…
