Rotation-driven transition into coexistent Josephson modes in an atomtronic dc-SQUID
D. M. Jezek, H. M. Cataldo
By means of a two-mode model, we show that transitions to different arrays of coexistent regimes in the phase space can be attained by rotating a double-well system, which consists…
dc to ac Josephson transition in a dc atom superconducting quantum interference device
H. M. Cataldo
We analyze the effect of the barrier motion on the Bose-Hubbard Hamiltonian of a ring-shaped Bose-Einstein condensate interrupted by a pair of Josephson junctions, a configuration…
Collisional dynamics of multiple dark solitons in a toroidal Bose-Einstein condensate: Quasiparticle picture
H. M. Cataldo, D. M. Jezek
We study the collisional dynamics of multiple dark solitons in a Bose-Einstein condensate confined by a toroidal trap. We assume a tight enough confinement in the radial direction…
Dynamics in multiple-well Bose-Einstein condensates
M. Nigro, P. Capuzzi, H. M. Cataldo +1
We study the dynamics of three-dimensional weakly linked Bose-Einstein condensates using a multimode model with an effective interaction parameter. The system is confined by a ring…
Effective two-mode model in Bose-Einstein condensates versus Gross-Pitaevskii simulations
Mauro Nigro, Pablo Capuzzi, Horacio M. Cataldo +1
We study the dynamics of three-dimensional Bose-Einstein condensates confined by double-well potentials using a two-mode model with an effective on-site interaction energy paramete…
Dark soliton collisions in a toroidal Bose-Einstein condensate
D. M. Jezek, P. Capuzzi, H. M. Cataldo
We study the dynamics of two gray solitons in a Bose-Einstein condensate confined by a toroidal trap with a tight confinement in the radial direction. Gross-Pitaevskii simulations…
