Parallel analog quantum simulation in homogeneous quantum gases

Diego Hernández Rajkov, Alberto Terenzi, Marcia Frómeta Fernández +4

Analog quantum simulation offers a powerful way to study strongly correlated quantum systems that are beyond the reach of classical computation. In this context, ultracold atomic g…

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…

Tuning the Critical Current in Toroidal Superfluids via Controllable Impurities

K. Xhani, G. Del Pace, N. Grani +4

We combine numerical and experimental approaches to study how impurities affect the maximum superflow in an annular Bose-Einstein condensate. By tuning the impurity density, we ach…

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…

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…

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…

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…

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…
