dc.description.abstract
Beutler-Fano resonances occuring in transport through a rectangular cavity are studied.<br />They emerge from the interaction of a resonant and a non-resonant path through the cavity.<br />Beutler-Fano resonances provide a means to measure the degree of decoherence present in the cavity.<br />Two different types of decoherence, microwave attenuation and dephasing according to the voltage probe model, are shown to have a characteristically different influence on Beutler-Fano resonances, characterized by a complex Fano q parameter.<br />We verify our theoretical results by measuring transport through microwave cavities made of three different materials, corresponding to a range of decoherence strengths.<br />The time-dependent propagation of a pulse through the rectangular cavity is investigated both theoretically and experimentally. In the time-resolved Fourier spectrum of the pulse transmitted through the cavity, transient hyperbolic interference patterns occur which allow for the extraction of resonance parameters.
