Symplectic integrators for spin systems
Robert I. McLachlan, Klas Modin, Olivier Verdier
We present a symplectic integrator, based on the canonical midpoint rule, for classical spin systems in which each spin is a unit vector in . Unlike splitting methods…

A minimal-variable symplectic integrator on spheres
Robert I. McLachlan, Klas Modin, Olivier Verdier
We construct a symplectic, globally defined, minimal-coordinate, equivariant integrator on products of 2-spheres. Examples of corresponding Hamiltonian systems, called spin systems…
