The Physics Institutes of Universität Leipzig present their joint report 2002. In the following, brief articles about the scientific activities and results are compiled. Key achievements in the Institutes for Experimental Physics were obtained in the fields of cell analysis with optical stretchers, laser-stimulated growth of nerve cells, pulsed field gradient NMR, confinement-induced relaxation processes in polymers, ion-beam nano-probes, acoustic microscopy, far-infrared magneto-ellipsometry, and preparation of high-quality epitaxial ZnO layers and nanowires. Highlights in the research of the Institute for Theoretical Physics were the study of non-commutative geometry (mathematical and physical aspects), critical behaviour of non-equilib...
