Query: Thermodynamics of the harmonic oscillator using coherent states   The ongoing discussion whether thermodynamic properties can be extracted from
a (possibly approximate) quantum mechanical time evolution using time averages
is fed with an instructive example. It is shown for the harmonic oscillator how
the Hilbert space or an appropriately defined phase space must be populated in
terms of coherent states in order to obtain the quantum result respectively the
classical one.
