The physical nature of low-lying energy levels of anharmonic oscillators is shown to be due to quantum reflections on (multiple) complex turning points. Mathematically, certain Stokes' lines linking complex-conjugate turning points may cross the real axis within the classically allowed region at poi
When one or several oscillators are anharmonic, an appropriate procedure is to calculate the set of energy levels of the anlurmonic uscilluturs by the WkB method from a knowledge of them potential energy function and to convolute the results with the smooth \(N(E)\) function calculated for the remai
A harmonic oscillator with time-dependent force constant when perturbed by a weak static quartic anharmonicity ti4, 1 small, is shown to generate new features in the dynamics. For weak coupling, both time-dependent perturbation theoretical analysis and near-exact numerical calculations predict that
