Tests der Lorentz-Invarianz mit makroskopischen Oszillatoren / Testing Lorentz Invariance with Macroscopic Oscillators
Prof. Dr. Stephan Schiller (Institut für Experimentalphysik, Univ. Düsseldorf)

The principle of Lorentz Invariance, including the isotropy of space, is an experimentally established fact and a foundation of the currently accepted theories of the fundamental forces. In the framework of the search for a fundamental unified theory of all forces, this principle is nevertheless under intense scrutiny: numerous new experiments and astronomical observations have been performed world-wide to explore whether this principle is perhaps only approximately valid.

In this talk I will give an overview of the concept and theories on Lorentz Invariance and describe the recent results [1] of our high-precision, Michelson-Morley-type experiment for testing Lorentz Invariance.
