Semiclassical matrix elements from periodic orbits
Physical Review A, 1992An extension of Gutzwiller's (1967, 1969, 1970, 1971, 1990) semiclassical theory for chaotic systems that allows a determination of matrix elements in terms of classical periodic orbits. Associated zeta functions are derived. The semiclassical predictions are found to be in good agreement with Fourier transforms of quantum spectra of hydrogen in a ...

Analytical Orbit Propagator Based on Vectorial Orbital Elements
AIAA Guidance, Navigation, and Control (GNC) Conference, 2013By using the vector orbital elements, namely the specific angular momentum and the eccentricity vectors, the first order short periodic equations of motion about an oblate planet are derived through a straightforward averaging technique. The results which are obtained are expressed in a coordinate-free form, and the singularity for low eccentricities ...

Time elements in Keplerian orbital elements
Celestial Mechanics, 1981Time elements are introduced in terms of Keplerian (classical) orbital elements for use with time transformations of the Sundman type. Three different time elements are introduced. One time element is associated with the eccentric anomaly, a second time element is associated with the true anomaly, and a third time element is associated with the ...

A set modified equinoctial orbit elements
Celestial Mechanics, 1985Modified equinoctial elements are introduced which are suitable for perturbation analysis of all kinds of orbit. Equations of motion in Lagrangian and Gaussian forms are derived. Identities connecting the partial derivatives of the disturbing function with respect to equinoctial elements are established.

On the equinoctial orbit elements
Celestial Mechanics, 1972This paper investigates the equinoctial orbit elements for the two-body problem, showing that the associated matrices are free from singularities for zero eccentricities and zero and ninety degree inclinations. The matrix of the partial derivatives of the position and velocity vectors with respect to the orbit elements is given explicitly, together ...
