Abstract
We theoretically investigate the cooling of a propagating phonon through Brillouin scattering. To that end, we propose to introduce an external viscous force using Brillouin scattering and an electro-optic feedback. Short delays feedback show an efficient control of the Brillouin linewidth whereas long delays can induce Fano-like resonances.

Comments
There is a mistake. The feedback can't be done with the AntiStokes frequency as the phonon thus generated has the wrong wavevector sign. One can inject a feedback light on the Stokes but the theory would be different and probably be more related to Brillouin Electro-Optic oscillators reducing the novelty of the manuscript
