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…
Emergence of magnetic excitations in one-dimensional quantum mixtures under confinement
Pablo Capuzzi, Patrizia Vignolo, Anna Minguzzi +1
We obtain an exact solution for the spectral function for one-dimensional Bose-Bose and Fermi- Fermi mixtures with strong repulsive interactions, valid in arbitrary confining poten…
Shortcut to spin dynamics for quantum mixtures
Pablo Capuzzi, Zehra Akdeniz, Patrizia Vignolo
The study of the long-time dynamics of quantum systems can be a real challenge, especially in systems like ultracold gases, where the required timescales may be longer than the lif…
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…
