Quantitative complementarity in two-path interferometry
A. Bramon, G. Garbarino, B. C. Hiesmayr
Abstract
The quantitative formulation of Bohr's complementarity proposed by Greenberger and Yasin is applied to some physical situations for which analytical expressions are available. This includes a variety of conventional double-slit experiments, but also particle oscillations, as in the case of the neutral-kaon system, and Mott scattering of identical nuclei. For all these cases, a unified description can be achieved including a new parameter, ν, which quantifies the effective number of fringes one can observe in each specific interferometric set-up.
