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 ...
Collective excitations of a one-dimensional quantum droplet Tylutki, Marek; Astrakharchik, Grigori; Malomed, Boris A.; Petrov, D. S. (2020-05-21)
Open AccessWe calculate the excitation spectrum of a one-dimensional self-bound quantum droplet in a two-component bosonic mixture described by the Gross-Pitaevskii equation (GPE) with cubic and quadratic nonlinearities. The cubic ...
