Mutual friction and vortex Hall angle in a strongly interacting Fermi superfluid
Nicola Grani, Diego Hernández-Rajkov, Cyprien Daix +8
The motion of a quantized vortex is intimately connected with its microscopic structure and the elementary excitations of the surrounding fluid. In this work, we investigate the tw…
Stabilizing persistent currents in an atomtronic Josephson junction necklace
Luca Pezzè, Klejdja Xhani, Cyprien Daix +7
Arrays of Josephson junctions are at the forefront of research on quantum circuitry for quantum computing, simulation and metrology. They provide a testing bed for exploring a vari…
Decay of persistent currents in annular atomic superfluids
Klejdja Xhani, Giulia Del Pace, Francesco Scazza +1
We investigate the role of vortices in the decay of persistent current states of annular atomic superfluids by solving numerically the Gross-Pitaevskii equation, and we directly co…
Connecting shear-flow and vortex array instabilities in annular atomic superfluids
D. Hernandez-Rajkov, N. Grani, F. Scazza +8
At the interface between two fluid layers in relative motion, infinitesimal fluctuations can be exponentially amplified, inducing vorticity and the breakdown of the laminar flow. T…
Repulsive Fermi and Bose Polarons in Quantum Gases
Francesco Scazza, Matteo Zaccanti, Pietro Massignan +2
Polaron quasiparticles are formed when a mobile impurity is coupled to the elementary excitations of a many-particle background. In the field of ultracold atoms, the study of the a…
Imprinting persistent currents in tunable fermionic rings
G. Del Pace, K. Xhani, A. Muzi Falconi +7
Persistent currents in annular geometries have played an important role in disclosing the quantum phase coherence of superconductors and mesoscopic electronic systems. Ultracold at…
