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…
Dirac equation in spacetimes with torsion and non-metricity
M. Adak, T. Dereli, L. H. Ryder
Dirac equation is written in a non-Riemannian spacetime with torsion and non-metricity by lifting the connection from the tangent bundle to the spinor bundle over spacetime. Foldy-…
Neutrino Oscillations Induced by Space-Time Torsion
M. Adak, T. Dereli, L. H. Ryder
The gravitational neutrino oscillation problem is studied by considering the Dirac Hamiltonian in a Riemann-Cartan space-time and calculating the dynamical phase. Torsion contribut…
Spin and Rotation in General Relativity
Lewis H. Ryder, Bahram Mashhoon
Rapporteur's Introduction to the GT8 session of the Ninth Marcel Grossmann Meeting (Rome, 2000); to appear in the Proceedings.
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…
On the interaction of massive spinor particles with external electromagnetic and torsion fields
Lewis H. Ryder, Ilya L. Shapiro
We explore the Dirac equation in external electromagnetic and torsion fields. Motivated by the previous study of quantum field theory in an external torsion field, we include a non…
Time-Independent Solutions to the Two-Dimensional Non-Linear O(3) Sigma Model and Surfaces of Constant Mean Curvature
M. S. Ody, L. H. Ryder
It is shown that time-independent solutions to the (2+1)-dimensional non- linear O(3) sigma model may be placed in correspondence with surfaces of constant mean curvature in three-…
