Symplectic Gaussian Process Regression of Hamiltonian Flow Maps

no code implementations11 Sep 2020 Katharina Rath, Christopher G. Albert, Bernd Bischl, Udo von Toussaint

In the limit of small mapping times, the Hamiltonian function can be identified with a part of the generating function and thereby learned from observed time-series data of the system's evolution.

Symplectic integration with non-canonical quadrature for guiding-center orbits in magnetic confinement devices

1 code implementation16 Mar 2019 Christopher G. Albert, Sergei V. Kasilov, Winfried Kernbichler

We study symplectic numerical integration of mechanical systems with a Hamiltonian specified in non-canonical coordinates and its application to guiding-center motion of charged plasma particles in magnetic confinement devices.
