Cooperative stabilization of persistent currents in superfluid ring networks
Marzena Ciszak, Nicola Grani, Diego Hernandez-Rajkov +3
Cooperative effects in oscillator networks are often associated with enhanced stability of phase-locked solutions, which increases with system size. We show that the stabilization…
Angular momentum of rotating fermionic superfluids by Sagnac phonon interferometry
Marcia Frómeta Fernández, Diego Hernández Rajkov, Giulia Del Pace +5
Fermionic many-body systems provide an unrivaled arena to investigate how interactions drive the emergence of collective quantum behavior, such as macroscopic coherence and superfl…
Microscopy of cavity-induced density-wave ordering in ultracold gases
Tabea Bühler, Aurélien Fabre, Gaia Bolognini +4
We demonstrate high-resolution in-situ imaging of density-wave ordering induced by cavity-mediated interactions in a unitary Fermi gas. We observe long-range spatial correlations t…
Measuring mutual friction in superfluids: the role of initial vortex configuration fluctuations
Nicola Grani, Diego Hernández-Rajkov, Marcia Frómeta Fernández +2
The physical origin of mutual friction in quantum fluids is deeply connected to the fundamental nature of superfluidity. It stems from the interaction between the superfluid and no…
Shapiro steps in strongly-interacting Fermi gases
Giulia Del Pace, Diego Hernández-Rajkov, Vijay Pal Singh +7
We report the observation of Shapiro steps in a periodically driven Josephson junction between strongly-interacting Fermi superfluids of ultracold atoms. We observe quantized plate…
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…
Tunneling transport of unitary fermions across the superfluid transition
G. Del Pace, W. J. Kwon, M. Zaccanti +2
We investigate the transport of a Fermi gas with unitarity-limited interactions across the superfluid phase transition, probing its response to a direct current (dc) drive through…
