Quantum dynamics of impurities in a one-dimensional Bose gas
Using a species-selective dipole potential, we create initially localized impurities and
investigate their interactions with a majority species of bosonic atoms in a one-dimensional …

Theory of superfluidity and drag force in the one-dimensional Bose gas
The one-dimensional Bose gas is an unusual superfluid. In contrast to higher spatial
dimensions, the existence of non-classical rotational inertia is not directly linked to the …
