  author={Hans Christian Andersen and Irwin Oppenheim and Kurt E. Shuler and George H. Weiss},
A relaxation process in which a dilute system is in weak interaction with a heat bath is termed canonically invariant if the time‐dependent system distribution function maintains its canonical form throughout the relaxation process and is thus characterized by a time‐dependent temperature. We discuss here the nonequilibrium (i.e., time‐dependent) thermodynamics of such canonically invariant relaxation processes. Explicit analytic forms are obtained for the partition functions Q(t), the system… CONTINUE READING
