 the probability distribution of the phase-space point of a system in equilibrium at temperature \(T\). (\(Z\) is a normalization constant called the partition function and \(k\) is Boltzmann’s constant.) This analogy has several facets: In both cases the probability distributions are naturally associated with their respective dynamical systems. In particular, these distributions are stationary or, what amounts to the same thing within the framework of Bohmian mechanics, equivariant. In both cases it seems natural to try to justify these equilibrium distributions by means of mixing-type, convergence-to-equilibrium arguments (Bohm 1953; Valentini &amp; Westman 2005). It has been argued, however, that in both cases the ultimate justification for these probability distributions must be in terms of statistical patterns exhibited by ensembles of actual subsystems within a typical individual universe (Bell 1981b, reprinted 1987c: 129; Dürr, Goldstein, &amp; Zanghì 1992a). And in both cases the status of, and justification for, equilibrium distributions remains controversial (Dürr &amp; Struyve 2020; see also Goldstein 2012).
