Momentum transfer in non-equilibrium steady states    [PDF]

Antoine Fruleux, Ryoichi Kawai, Ken Sekimoto

When a Brownian object interacts with non-interacting gas particles under
non-equilibrium conditions, the energy dissipation associated to the Brownian
motion causes an additional force on the object as a `momentum transfer
deficit'. This principle is demonstrated first by a new NESS model and then
applied to several known models such as adiabatic piston for which simple
explanation has been lacking.
