Relative dynamics of quantum vortices and massive cores in binary BECs
Alice Bellettini, Andrea Richaud, Vittorio Penna
We study the motion of superfluid vortices with filled massive cores. Previous point-vortex models already pointed out the impact of the core mass on the vortex dynamical propertie…
Dynamics of a massive superfluid vortex in confining potentials
Andrea Richaud, Pietro Massignan, Vittorio Penna +1
We study the motion of a superfluid vortex in condensates having different background density profiles, ranging from parabolic to uniform. The resulting effective point-vortex mode…
Dynamics of massive point vortices in binary mixture of Bose-Einstein condensates
Andrea Richaud, Vittorio Penna, Alexander L. Fetter
We study the massive point-vortex model introduced in Ref. [Phys. Rev. A 101, 013630 (2020)], which describes two-dimensional point vortices of one species that have small cores of…
Geometrical aspects in the analysis of microcanonical phase-transitions
Ghofrane Bel-Hadj-Aissa, Matteo Gori, Vittorio Penna +2
In the present work, we discuss how the functional form of thermodynamic observables can be deduced from the geometric properties of subsets of phase space. The geometric quantitie…
Quantum-granularity effect in the formation of supermixed solitons in ring lattices
Andrea Richaud, Vittorio Penna
We investigate a notable class of states peculiar to a bosonic binary mixture featuring repulsive intraspecies and attractive interspecies couplings. We evidence that, for small va…
Vortices with massive cores in a binary mixture of Bose-Einstein condensates
Andrea Richaud, Vittorio Penna, Ricardo Mayol +1
We analyze a notable class of states relevant to an immiscible bosonic binary mixture loaded in a rotating box-like circular trap, i.e. states where vortices in one species host th…
