Abstract
From Bohm’s interpretation of Quantum Mechanics, a quantum kinetic equation (QKE) can be derived. It is found that waves propagate in force-free gases of non interacting particles, only due to Bohm potential. In the present article the existence of Landau damping in such propagations is investigated. It is found that Bohm potential alone gives indeed rise to damping entirely analogous to classical Landau damping, both for bosons and for weakly degenerate fermions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
