Majorana Neutrinos in Sandwich Wave Spacetimes: Flavor Modulation and Helicity Transitions
Yorgo Senikoglu
We present the propagation of massive Majorana neutrinos crossing an exact gravitational sandwich wave background. By employing a Takagi factorization to decouple the matrix field…

An Explicit Kaluza-Klein Reduction of Einstein's Gravity in on
Tekin Dereli, Yorgo Senikoglu
We study a six-dimensional Kaluza-Klein theory with spacetime topology and analyze the gauge sector arising from dimensional reduction. Using normalized Killing ve…

Scattering of massive neutrino test fields from a gravitational pulse
Tekin Dereli, Yorgo Senikoglu
Linearized Einstein-Weyl equations are solved precisely in the context of sandwich gravitational waves. The neutrino's energy-momentum depends on the geometry and composition of th…
