Abstract
A new optical effect in the transport of atoms in dense gases, capillaries, and porous media is predicted. The origin of this effect lies in superelastic collisions of excited atoms, which give rise to thermal diffusion processes. Model estimates are made for the magnitude of the effects in the absence of flows and in the presence of flows in capillary systems. It is shown that under certain assumptions regarding superelastic collisions of atoms with the walls, the optical effect changes the transmission of a capillary.
