Variational Field Equations of a Majorana Neutrino Coupled to Einstein's Theory of General Relativity
Tekin Dereli, Yorgo Senikoglu
A consistent variational derivation of the Majorana 4-spinor field equations coupled to Einstein's theory of gravitation is given. The equivalence of the first and the second order…

Neutrino Fields in a Sandwich Gravitational Wave Background
Tekin Dereli, Ozay Gurtug, Mustafa Halilsoy +1
Sandwich gravitational waves are given globally in terms of step functions at the boundaries. Linearized Einstein-Weyl equations are solved exactly in this background in Rosen coor…
