WebApr 7, 2024 · We study spin and flavor oscillations of astrophysical neutrinos under the influence of external fields in curved spacetime. First, we consider spin oscillations in case of neutrinos gravitationally scattered off a rotating supermassive black hole surrounded by a thin magnetized accretion disk. We find that the gravitational interaction only does not … WebMar 5, 2024 · The electromagnetic field has a stress-energy tensor associated with it. From our study of electromagnetism we know that the electromagnetic field has energy density U = (E2 + B2) / 8πk and momentum density →S = (→E × →B) / 4πk (in units where c = 1, with k being the Coulomb constant). This fixes the components of the stress-energy ...

By means of E = m c 2, having energy means, in some sense, having mass, and hence the ...
WebThe tetrad formalism is an approach to general relativity that generalizes the choice of basis for the tangent bundle from a coordinate basis to the less restrictive choice of a local basis, i.e. a locally defined set of four linearly independent vector fields called a tetrad or vierbein. It is a special case of the more general idea of a vielbein formalism, which is set …
