Der Forschungsbericht der Institute für Experimentelle Physik I und II und des Instituts für Theoretische Physik erscheint jährlich und berichtet über die Aktivitäten und die Mitarbeiter der Institute. Den Hauptteil des Forschungsbericht bilden Forschungsberichte aus den einzelnen Abteilungen der Institute (Halbleiterphysik, Magnetismus, Optik und Akustik).

The Institute for Experimental Physics II of Universität Leipzig welcomes you to read its activity report 2001. In the following some statistics about the structure of the institute, the people involved, and the teaching activities are summarized. The core of the report is built by the scientific activity reports - arranged according to the groups making up the institute: solid-state optics and acoustics, semiconductor physics, nuclear solid-state physics, physics of dielectric solids, superconductivity and magnetism.

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-equilibrium phase transitions, Monte Carlo studies of a large variety of systems and the renormalization group flow of low dimensional systems. We invite you to look for further details in the report.

In this report the Institutes of Physics of the Universität Leipzig present their scientific activities and major achievements in the year 2003.

The three Institutes of Physics of Universität Leipzig present their joint research report covering the year 2004. It documents the scientific progress made in various fields. The year has brought intensified collaboration within and between the Physics Institutes and with the outside world.
