Bose superfluids at finite temperatures. We make use of a minimal model in which particles obey Newtonian dynamics
and their equations of motion are self-consistently coupled with the Gross-Pitaevskii equation.
We characterize the effective drag force acting on the particles at finite
temperatures and study their interaction with vortices in both simple and turbulent
environment. In particular, we elucidate the role played by the drag-force, mutual-friction and the Magnus force.
