Abstract: We report on the experimental investigation of the properties of the eigenvalues and wavefunctions and the fluctuation properties of the scattering matrix of closed and open billiards, respectively, of which the classical dynamics undergoes a… read more here.

Abstract: We investigate the classical nonrelativistic dynamics of three bodies in Efimov's $\ensuremath{-}1/{R}^{2}$ potential in three spatial dimensions, with a view towards semiclassical quantization and insight into the geometry of Efimov states. Without the short-distance cutoff,… read more here.
