      abstract     = {Stokes drift is a classical fluid effect in which traveling
                      waves transfer momentum to tracers of the fluid, resulting
                      in a nonzero drift velocity in the direction of the incoming
                      wave; this effect is the driving mechanism allowing
                      particles, i.e., impurities, to be transported by the flow.
                      In a classical (viscous) fluid this happens usually due to
                      the presence of viscous drag forces; because of the eventual
                      absence of viscosity in quantum fluids, impurities are
                      driven by inertial effects and pressure gradients only. We
                      present theoretical predictions of a Stokes drift analogous
                      in quantum fluids finding that, at the leading order, the
                      drift direction and amplitude depend on the initial impurity
                      position with respect to the wave phase, and at the second
                      order, our theoretical model recovers the classical Stokes
                      drift but with a coefficient that depends on the relative
                      particle-fluid density ratio. Our theoretical predictions
                      are obtained for classical impurities using multitime
                      analytical asymptotic expansions. Numerical simulations of a
                      two-dimensional Gross-Pitaevskii equation coupled with a
                      classical impurity corroborate our findings. Our findings
                      are experimentally testable, for instance, using fluids of
                      light obtained in photorefractive crystals.},
