RELATED WORKS

In my earlier work with Patrick Farrell, we developed integrators for ODE systems that preserve arbitrarily many invariants. This works uses the framework of this idea, but adapts it to the preservation of adiabatic invariants; one adiabatic invariant in particular: the magnetic moment.
