Driven impurity in an ultracold 1D Bose gas with intermediate interaction strength

Abstract:
We study a single impurity driven by a constant force through a one-dimensional Bose gas using a LiebLiniger based approach. Our calculaton is exact in the interaction amongst the particles in the Bose gas, and is perturbative in the interaction between the gas and the impurity. In contrast to previous studies of this problem, we are able to handle arbitrary interaction strength for the Bose gas. We find very good agreement with recent experiments [Phys. Rev. Lett. 103, 150601 (2009)].
