A Symplectic Integrator for Hill’s Equations
Hill’s equations are an approximation that is useful in a number of areas of astrophysics including planetary rings and planetesimal disks. We derive a symplectic method for integrating Hill’s equations based on a generalized leapfrog. This method is implemented in the parallel N -body code, PKDGRAV and tested on some simple orbits. The method demonstrates a lack of secular changes in orbital e...
متن کاملA Symplectic Integrator for Riemannian Manifolds l
There exist a number of mechanical systems having configuration and phase spaces that are differentiable manifolds which are not open subsets of Euclidean space. The spherical pendulum, which has configuration space the 2-sphere, and a single rigid body, with configuration space the Lie group SO(3), are two common examples. Integration algorithms, on the other hand, are usually set in the Eucli...
متن کاملA Symplectic Integrator for Riemannian Manifolds
The connguration spaces of mechanical systems usually support Riemannian metrics which have a explicitly solvable geodesic ows and parallel transport operators. While not of primary interest, such metrics can be used to generate integration algorithms by using the known parallel transport to evolve points in velocity phase space.
متن کاملAnomaly in Symplectic Integrator
Effective Liouville operators of the firstand the second-order symplectic integrators are obtained for the one-dimensional harmonic-oscillator system. The operators are defined only when the time step is less than two. Absolute values of the coordinate and the momentum monotonically increase for large time steps. PACS numbers: 05.10.-a, 02.10.Hh
متن کاملA minimal-variable symplectic integrator on spheres
We construct a symplectic, globally defined, minimal-variable, equivariant integrator on products of 2-spheres. Examples of corresponding Hamiltonian systems, called spin systems, include the reduced free rigid body, the motion of point vortices on a sphere, and the classical Heisenberg spin chain, a spatial discretisation of the Landau–Lifshitz equation. The existence of such an integrator is ...
