Abstract
t is shown that a fast sweep of a Josephson tunnel junction can reveal the presence of quantum energy levels in the associated washboard potential. Peculiar effects, that can be observed on P(I) and Γ(I), are obtained by numerical integration of the whole time dependent master equation describing the dynamics of the statistical population of each quantum level.File in questo prodotto:
