Abstract
The quantum discrete self-trapping equation with three degrees of freedom is investigated. Numerically evaluated eigenvalues are shown to exhibit the avoided-crossing phenomenon. The nearest-neighbour level spacing distributions for symmetric states corresponding to three particular choices of parameter values are shown to be consistent with a semiclassical conjecture by Berry and Robnik (1984).File in questo prodotto:
