Autoparallel orbits in Kerr Brans-Dicke spacetimes
H. Cebeci, T. Dereli, R. W. Tucker
The bounded orbital motion of a massive spinless test particle in the background of a Kerr Brans-Dicke geometry is analysed in terms of worldlines that are auto-parallels of differ…
An action principle for the quantization of parametric theories and nonlinear quantum cosmology
Charles H-T Wang, Smaragda Kessari, Edward R Irvine
By parametrizing the action integral for the standard Schrodinger equation we present a derivation of the recently proposed method for quantizing a parametrized theory. The reformu…
Field-Particle Dynamics in Spacetime Geometries
Robin W. Tucker
With the aid of a Fermi-Walker chart associated with an orthonormal frame attached to a time-like curve in spacetime, a discussion is given of relativistic balance laws that may be…
Nonlinear parametric quantization of gravity and cosmological models
Charles Wang
A generalization of the recently formulated nonlinear quantization of a parameterized theory is presented in the context of quantum gravity. The parametric quantization of a Friedm…
On the motion of spinning test particles in plane gravitational waves
M Mohseni, Robin W Tucker, Charles Wang
The Mathisson-Papapetrou-Dixon equations for a massive spinning test particle in plane gravitational waves are analysed and explicit solutions constructed in terms of solutions of…
A nonlinear quantum model of the Friedmann universe
Charles Wang
A discussion is given of the quantisation of a physical system with finite degrees of freedom subject to a Hamiltonian constraint by treating time as a constrained classical variab…
