Smooth time-dependent control of dipolar Bose-Einstein condensates
Chris Whitty, Aitor Alaña, Michele Modugno +4
We consider protocols for control of dipolar Bose-Einstein condensates where the critical role is played by the long-range anisotropic interatomic magnetic dipole-dipole interactio…
Vortex dynamics in rotating dipolar supersolids across Josephson and self-trapping regimes
Aitor Alaña, Michele Modugno, Pablo Capuzzi
We investigate vortex nucleation and transport in a rotating dipolar supersolid arranged in a triangular droplet lattice, exploiting its description as an array of weakly linked co…
Self-sustained Josephson dynamics and self-trapping in supersolids
Aitor Alaña, Michele Modugno, Pablo Capuzzi +1
We explore the self-sustained Josephson junction dynamics in dipolar supersolids, predicting the possibility of self-trapping alongside the experimentally observed Josephson oscill…
Phase-induced vortex pinning in rotating supersolid dipolar systems
Aitor Alaña, Michele Modugno, Pablo Capuzzi +1
We analyze the pinning of vortices for a stationary rotating dipolar supersolid along the low-density paths between droplets as a function of the rotation frequency. We restrict ou…
Supersolid formation time shortcut and excitation reduction by manipulating the dynamical instability
Aitor Alaña
Supersolids are a phase of matter exhibiting both superfluidity and a periodic density modulation typical of crystals. When formed via quantum phase transition from a superfluid, t…
Supersolid formation in a dipolar condensate by roton instability
Aitor Alaña, Iñigo L. Egusquiza, Michele Modugno
We characterize the role of the roton instability in the formation of a supersolid state of an elongated dipolar condensate, following a quench of the contact interactions across t…
Crossing the superfluid-supersolid transition of an elongated dipolar condensate
Aitor Alaña, Nicolò Antolini, Giulio Biagioni +2
We provide a theoretical characterization of the dynamical crossing of the superfluid-supersolid phase transition for a dipolar condensate confined in an elongated trap, as observe…
