Wave propagation and landau-type damping in quantum liquids

ABSTRACT

Starting from Bohm’s point of view on Quantum Mechanics, adopting the Bohm potential description, a Quantum Kinetic Equation can be derived. When molecular interactions are described as a self-consistent field, a Quantum Vlasov Equation (QVE) can be written. With this QVE, the evolution of a small perturbation can be described, yielding a wave propagation with or without a damping coefficient, depending on conditions. With this approach applied to a liquid of either fermions or bosons, the propagation of waves in quantum liquids is described.
