Correlations in S-Waves — •Rüdiger Mack, Alexander Wolf, Karl Vogel, and Wolfgang P. Schleich — Abteilung für Quantenphysik, Universität Ulm, Germany

An s-state consists mainly of interference. Wigner functions express the interference nature of quantum mechanics in negative domains of phase space. These domains strongly depend on the number of dimensions and manifest themselves in the time evolution of the average separation ⟨ r⟩ of the s-wave from the origin. Especially in D=2 dimensions the wave first contracts and then expands. We investigate different initial s-waves in order to enlarge this contraction effect. Moreover we address the question of the existence of an optimum wave function.
