Abstract: I will describe how one can generalize the Archimedean principle to general "objects" immersed in fluids, including for example quantum particles or localized perturbations of the fluids themselves. As an application, I will present a general formula for the mass transported by a sound wave and discuss the peculiar effects its generalization implies for more exotic excitations such as rotons in superfluid liquid helium. |
