Jc. Crepeau et H. Herzel, COMPARISON OF SPECTRAL ENTROPY WITH STATISTICAL ENTROPY IN SELECTED PHYSICAL SYSTEMS, Journal of non-equilibrium thermodynamics, 21(2), 1996, pp. 169-174
In an attempt to find a connection between the statistical entropy and
the spectral entropy proposed by Powell and Percival, these propertie
s are explicitly computed and compared for three different systems: Br
ownian motion of a particle in a fluid, Brownian motion in a harmonic
potential, and the photon gas. It is shown that in these systems the s
tatistical and the spectral entropy compare weakly since they quantify
different statistical aspects.
