This experimental work was carried out in collaboration with Associate Professor Sevick’s group. There have now been a large number of experimental confirmations of the Evans-Searles FT. In every case, however, the system studied could be accurately modelled by the Langevin Equation with white noise. This work gave the first experimental confirmation of the FT for a system that cannot be modeled by such an equation. The paper describing the work was singled out and advertised by Institute of Physics editors for its “novelty, signficance and potential impact on future research”.
