Abstract
Two superconducting microwave billiards have been electromagnetically coupled in a variable way. The spectrum of the entire system has been measured and the spectral statistics analyzed as a function of the cou pling strength. It is shown that the results can be understood in term s of a random matrix model of quantum mechanical symmetry breaking-as, e.g., the violation of parity or isospin in nuclear physics.
