Aspects of universally valid Heisenberg uncertainty relation
Kazuo Fujikawa, Koichiro Umetsu
A numerical illustration of a universally valid Heisenberg uncertainty relation, which was proposed recently, is presented by using the experimental data on spin-measurements by J.…
Electromagnetic interaction in theory with Lorentz invariant CPT violation
Masud Chaichian, Kazuo Fujikawa, Anca Tureanu
An attempt is made to incorporate the electromagnetic interaction in a Lorentz invariant but CPT violating non-local model with particle-antiparticle mass-splitting, which is regar…
On neutrino masses via CPT violating Higgs interaction in the Standard Model
Masud Chaichian, Kazuo Fujikawa, Anca Tureanu
The Lorentz invariant violation by using non-local interactions is naturally incorporated in the Higgs coupling to neutrinos in the Standard Model, without spoiling the basic…
A universally valid Heisenberg uncertainty relation
Kazuo Fujikawa
A universally valid Heisenberg uncertainty relation is proposed by combining the universally valid error-disturbance uncertainty relation of Ozawa with the relation of Robertson. T…
Lorentz-invariant CPT violation
Masud Chaichian, Kazuo Fujikawa, Anca Tureanu
A Lorentz-invariant CPT violation, which may be termed as long-distance CPT violation in contrast to the familiar short-distance CPT violation, has been recently proposed. This sch…
Does CHSH inequality test the model of local hidden variables?
Kazuo Fujikawa
It is pointed out that the local hidden variables model of Bell and Clauser-Horne-Shimony-Holt (CHSH) gives or for the quantum CHSH operator $B=…
