Scattering of a massive quantum vortex-dipole from an obstacle
Alice Bellettini, Enrico Ortu, Vittorio Penna
In binary mixtures of Bose-Einstein condensates, massive-vortex dipoles can arise, and undergo scattering processes against obstacles. These show an intriguing dynamics, governed b…

Supercurrents and tunneling in massive many-vortex necklaces and star-lattices
Alice Bellettini, Vittorio Penna
Recently, cold atoms mixtures have attracted broad interest due to their novel properties and exotic quantum effects with respect to single-component systems. In this paper the foc…

Massive-vortex realization of a Bosonic Josephson Junction
Alice Bellettini, Andrea Richaud, Vittorio Penna
We study the mass exchange between two rotating, quantum massive vortices in a two-component Bose-Einstein condensate. The vortices, in the majority component, exhibit a filled cor…
