Onsager's theorem

Web2. 4. 2 The Onsager Relations. The thermodynamics of irreversible processes postulates that, when local entropy production is represented as a sum of products of fluxes and forces, both must be linearly related to each other [ 22 ].

Rev. A 36, 222 (1987)] is reviewed. An explicitly soluble Langevin problem is shown to violate Onsager’s original symmetry but to obey the generalized theorem. The physical content of the generalized Onsager symmetry is discussed from the point of view of Nosé–Hoover …
