Abstract:
We study two entropies of a system composed of two coupled harmonic oscillators which isbrought to a canonical thermal equilibrium with a heat-bath at temperature T . Using the purityfunction, we explicitly determine the Rényi and van Newmon entropies in terms of different physicalparameters. We will numerically analyze these two entropies under suitable conditions and showtheir relevance.
