| Résumé : | The approach to equilibrium of an assembly of rotating dipoles on a rigid lattice is studied along the lines of the general statistical thoery of irreversible processes developed by Prigogine and his coworkers. To simplify the problem we restrict ourselves to the case of a two-dimensional system. The long-time behaviour of the distribution function of the angular momenta of the dipoles is discussed. It is shown that two-dipole interaction processes are unable to drive the system to equilibrium: they only tend to symmetrize the distribution function in all variables. The system will actually reach its equilibrium state through interactions involving three dipoles or more. Two-dipole interaction processes may still play an important role in the case of Brownian motion. © 1957. |
