Andreev-Bashkin effect in superfluid cold gases mixtures Nespolo, Jacopo; Astrakharchik, Grigori; Recati, Alessio (2017-12-05)
Open Access© 2017 The Author(s). Published by IOP Publishing Ltd on behalf of Deutsche Physikalische Gesellschaft. We study a mixture of two superfluids with density-density and current-current (Andreev-Bashkin) interspecies interactions. ...
Coherent oscillations in small Fermi-polaron systems Tylutki, Marek; Astrakharchik, Grigori; Recati, Alessio (AMER PHYSICAL SOC, 2017-12-01)
Open AccessWe study the ground state and excitations of a one-dimensional trapped polarized Fermi gas interacting with a single impurity. First, we study the tunneling dynamics of the impurity through a potential barrier, such as one ...
Repulsive Fermi polarons in a resonant mixture of ultracold 6Li atoms Scazza, F; Valtolina, G; Massignan, Pietro Alberto; Recati, Alessio; Amico, A; Burchianti, A; Fort, C; Inguscio, M; Zaccanti, M; Roati, G (2017)
Open AccessWe employ radio-frequency spectroscopy to investigate a polarized spin mixture of ultracold 6 Li atoms close to a broad Feshbach scattering resonance. Focusing on the regime of strong repulsive interactions, we observe ...
