Sound propagation in striped supersolid cold gases at zero temperature
Elena Poli, Giovanni I. Martone, Sandro Stringari +1
We present a unified hydrodynamic approach for the sound propagation in the stripe phases realized in ultracold dipolar gas and spin-orbit-coupled BEC platforms at zero temperature…
Anomalous Doppler effect in two-component Bose-Einstein condensates
Tomasz ZawiÅlak, Sandro Stringari, Alessio Recati
We show that two-component Bose-Einstein condensed mixtures, in presence of a persistent current, exhibit a non trivial Doppler shift of the sound velocities. The peculiarity is du…
Heisenberg Uncertainty Inequality and Breaking of Isospin Symmetry in Atomic Nuclei
Sandro Stringari
The Heisenberg uncertainty inequality is used to derive a rigorous lower bound to the amount of isospin impurities in atomic nuclei, caused by the violation of isospin symmet…
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…
Anomalous Doppler effect in superfluid and supersolid atomic gases
Tomasz ZawiÅlak, Marija Å indik, Sandro Stringari +1
By employing the formalism of hydrodynamics, we derive novel analytic predictions for the Doppler effect in superfluids with broken Galilean invariance and hosting persistent curre…
