Nuclear Structure and Quantum Chaos

Hans Weidenmueller, Max-Planck-Institut für Kernphysik, Heidelberg (Germany)
Building 6008 Conference Room

Chaos reigns when the spectral fluctuation properties of a quantum system agree with predictions of random-matrix theory. The evidence for such agreement in nuclei is reviewed. Once established, quantum chaos is useful for the analysis of data (examples: isospin and parity violation). Chaos is a generic feature of nuclear dynamics and, more generally, of interacting fermionic many-body systems. This statement is not in disagreement with known regular features such as the shell model or the collective models.
