Parallel analog quantum simulation in homogeneous quantum gases
Diego Hernández Rajkov, Alberto Terenzi, Marcia Frómeta Fernández +4
The paper demonstrates a multiplexed analog quantum simulator using a single ultracold atomic cloud, enabling independent control of multiple simulation units for studies of superf…
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…
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…
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…
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…
