Can ponderomotive force induce motion in neutral gas?

[Tominator]

Ponderomtive force is well known phenomenon, able to accelerate particles of all charges in plasma, but what about neutral gas? If we omit thermodynamics for a while and consider a perfectly non-ionizable gaseous dielectric, would polarisation be enough to induce motion in it?
Thanks for answers

PS: Not considering the motion due to heating the gas because of polarisation losses...

No, polarisation alone would not be enough to induce motion in a neutral gas. The reason for this is that the polarization of a dielectric does not create a force on the molecules of the gas, but rather creates an electric field in the space around them. This electric field can then create forces on charged particles, which can cause them to move, but there are no forces on the neutral molecules themselves.
