Hardy's Paradox and Measurement-disturbance Relations
Kazuo Fujikawa, C. H. Oh, Sixia Yu
We establish a quantitative relation between Hardy's paradox and the breaking of uncertainty principle in the sense of measurement-disturbance relations in the conditional measurem…
A hidden-variables version of Gisin's theorem
Kazuo Fujikawa, Koichiro Umetsu
It is generally assumed that {\em local realism} represented by a noncontextual and local hidden-variables model in such as the one used by Bell always gives rise to CHSH ine…
Neutrino-antineutrino mass splitting in the Standard Model and baryogenesis
Kazuo Fujikawa, Anca Tureanu
On the basis of a previously proposed mechanism of neutrino-antineutrino mass splitting in the Standard Model, which is Lorentz and invariant but non-local to ev…
Heisenberg Uncertainty Relation Revisited
Kazuo Fujikawa
It is shown that all the known uncertainty relations are the secondary consequences of Robertson's relation. The basic idea is to use the Heisenberg picture so that the time develo…
