The weak gravitational field expansion method to account for the gravitationally induced neutrino oscillation effect is critically examined, then it is shown that the splitting of the neutrino phase into a “kinematic” and a “gravitational” phase is not always possible because the relativistic factor modifies the particle interference phase splitting condition in a gravitational field. key words...

We revisit the issue of memory effects, i.e. effects giving rise to a net cumulative change configuration test particles, using toy model describing emission radiation by compact source and focusing on scalar, hence non-radiative, part Riemann curvature. Motivated well known fact that gravitational is accompanied effect, permanent displacement relative separation present after has passed, we in...

The present paper is intended for studying the effect of strong gravitational lensing in context charged wormhole. To study this effect, conditions determining existence photon spheres at and outside throat are obtained. necessary sufficient or wormhole derived. Furthermore, investigated three cases different forms redshift function. These include effective (i) throat, (ii) (iii) both throat. C...

the isotropy and constancy of the speed of light, the time dilation (or Doppler effect), the universality of the gravitational redshift with various combinations of high precision clocks. Furthermore, laser tracking and a laser link allows a strongly improved measurement of the gravitomagnetic Lense–Thirring effect, of the gravitoelectric Einstein perigee advance, of the gravitational redshift,...
