Abstract

We study two entropies of a system composed of two coupled harmonic oscillators which is

brought to a canonical thermal equilibrium with a heat-bath at temperature T . Using the purity

function, we explicitly determine the Rényi and van Newmon entropies in terms of different physical

parameters. We will numerically analyze these two entropies under suitable conditions and show

their relevance.
