Abstract. We derive a master equation for the motion of a polarizable particle

weakly interacting with one or several strongly pumped cavity modes. We

focus here on massive particles with a complex internal structure, such as

large molecules and clusters, for which we assume a linear scalar polarizability

mediating the particle–light interaction. The predicted friction and diffusion

coefficients are in good agreement with former semiclassical calculations for

atoms and small molecules in weakly pumped cavities, while the current rigorous

quantum treatment and numerical assessment sheds light on the feasibility of

experiments that aim to optically manipulate beams of massive molecules with

multimode cavities.
