Statistical-mechanical description of classical test-particle dynamics in the presence of an external force field: modelling noise and damping from first principles
I. Kourakis, A. P. Grecos
Aiming to establish a rigorous link between macroscopic random motion (described e.g. by Langevin-type theories) and microscopic dynamics, we have undertaken a kinetic-theoretical…

Generalized Moyal structures in phase space, kinetic equations and their classical limit: II. Applications to harmonic oscillator models
C. Tzanakis, A. P. Grecos, P. Hatjimanolaki
The formalism of generalized Wigner transformations developped in a previous paper, is applied to kinetic equations of the Lindblad type for quantum harmonic oscillator models. It…

Generalized Moyal structures in phase space, kinetic equations and their classical limit: I. General Formalism
Constantinos Tzanakis, Alkis P. Grecos
Generalised Wigner and Weyl transformations of quantum operators are defined and their properties, as well as those of the algebraic structure induced on the phase-space are studie…
