It is proposed to shoot a molecule through a pipe of mesoscopic scale. The molecule should effectifely carry two spins and antiferromagnetic chains should be embedded in the wall of the tube. If the momentum is detected before and behind…
Consider a measurement in which the current coming out of a mesoscopic sample is filtered around a given frequency, amplified, measured and squared. Then this process is repeated many times and the results are averaged. Often, two such…

Consistent with the predictions of Kibble and Zurek, scaling behaviour has been seen in the production of fluxoids during temperature quenches of superconducting rings. However, deviations from the canonical behaviour arise because of…
