Summary: The asymptotics of the weighted \(L_{p}\)-norms of Hermite polynomials, which describes the Rényi entropy of order \(p\) of the associated quantum oscillator probability density, is determined for \(n\to\infty\) and \(p>0\). Then, it is applied to the calculation of the Rényi entropy of the quantum-mechanical probability density of the highly-excited (Rydberg) states of the isotropic oscillator.
