Neutron interference in the Earth's gravitational field
Andrei Galiautdinov, Lewis H. Ryder
This work relates to the famous experiments, performed in 1975 and 1979 by Werner et al., measuring neutron interference and neutron Sagnac effects in the earth's gravitational fie…

Possible effects of spacetime non-metricity on neutrino oscillations
M. Adak, T. Dereli, L. H. Ryder
The contribution of gravitational neutrino oscillations to the solar neutrino problem is studied by constructing the Dirac Hamiltonian and calculating the corresponding dynamical p…

The Gordon decompositions of the inertial currents of the Dirac electron correspond to a Foldy-Wouthuysen transformation
Ingo Kirsch, Lewis H. Ryder, Friedrich W. Hehl
We consider Dirac's free electron theory on the first quantized level. We decompose its canonical spin current á la Gordon and find a conserved ``Gordon spin'' current which turns…
