Schwarzschild horizon and the gravitational redshift formula
Edward Malec
The gravitational redshift formula is usually derived in the geometric optics approximation. In this note we consider an exact formulation of the problem in the Schwarzschild space…
Is Einstein's equivalence principle valid for a quantum particle?
Andrzej Herdegen, Jaroslaw Wawrzycki
Einstein's equivalence principle in classical physics is a rule stating that the effect of gravitation is locally equivalent to the acceleration of an observer. The principle deter…
Backscattering of electromagnetic and gravitational waves off Schwarzschild geometry
Janusz Karkowski, Edward Malec, Zdobysław Świerczyński
Major changes in Sec. II (with much stronger estimates), minor changes in remaining sections, a new title. Deleted Appendix, added 2 new references.
Symmetry properties of the metric energy-momentum tensor in classical field theories and gravity
Guido Magnano, Leszek M. Sokolowski
We derive a generic identity which holds for the metric (i.e. variational) energy-momentum tensor under any field transformation in any generally covariant classical Lagrangian fie…
Can Schwarzschildean gravitational fields suppress gravitational waves?
Edward Malec, Gerhard Schaefer
Gravitational waves in the linear approximation propagate in the Schwarzschild spacetime similarly as electromagnetic waves. A fraction of the radiation scatters off the curvature…
