On Accelerated Inertial Frames in Gravity and Electromagnetism
D. Lynden-Bell, J. Bicak, J. Katz
When a charged insulating spherical shell is uniformly accelerated, an oppositely directed electric field is produced inside. Outside the field is the Born field of a uniformly acc…
Chaotic motion in pp-wave spacetimes
J. Podolsky, K. Vesely
We investigate geodesics in non-homogeneous vacuum pp-wave solutions and demonstrate their chaotic behavior by rigorous analytic and numerical methods. For the particular class of…
Interpreting a conformally flat pure radiation space-time
J. B. Griffiths, J. Podolsky
A physical interpretation is presented of the general class of conformally flat pure radiation metrics that has recently been identified by Edgar and Ludwig. It is shown that, at l…
Boosted static multipole particles as sources of impulsive gravitational waves
J. Podolsky, J. B. Griffiths
It is shown that the known solutions for nonexpanding impulsive gravitational waves generated by null particles of arbitrary multipole structure can be obtained by boosting the Wey…
Symmetries of asymptotically flat electrovacuum spacetimes and radiation
J. Bicak, A. Pravdova
Symmetries compatible with asymptotic flatness and admitting gravitational and electromagnetic radiation are studied by using the Bondi-Sachs-van der Burg formalism. It is shown th…
Non-expanding impulsive gravitational waves
J. Podolsky
We investigate a class of impulsive gravitational waves which propagate either in Minkowski or in the (anti-)de Sitter background. These waves are constructed as impulsive members…
Chaos in pp-wave spacetimes
J. Podolsky, K. Vesely
We demonstrate chaotic behavior of timelike, null and spacelike geodesics in non-homogeneous vacuum pp-wave solutions. This seems to be the first known example of a chaotic motion…
Smooth sandwich gravitational waves
J. Podolsky
Gravitational waves which are smooth and contain two asymptotically flat regions are constructed from the homogeneous pp-waves vacuum solution. Motion of free test particles is cal…
Continuous coordinates for all impulsive pp - waves
J. Podolsky, K. Vesely
We present a coordinate system for a general impulsive gravitational pp - wave in vacuum in which the metric is explicitly continuous, synchronous and "transverse". Also, it is mor…
New examples of sandwich gravitational waves and their impulsive limit
J. Podolsky, K. Vesely
Non-standard sandwich gravitational waves are constructed from the homogeneous pp vacuum solution and the motions of free test particles in the space-times are calculated explicitl…
Interpretation of the Siklos solutions as exact gravitational waves in the anti-de Sitter universe
J. Podolsky
The Siklos class of solutions of Einstein's field equations is investigated by analytical methods. By studying the behaviour of free particles we reach the conclusion that the spac…
