Dominant interaction Hamiltonians — •Martin Gerlach and Jan-Michael Rost — Max-Planck-Institute for the Physics of Complex Systems, Dresden, Germany

Generic Hamiltonian systems do not show an obvious perturbative part, which makes it difficult to understand (or even calculate) their dynamics. Finding suitable approximations to such systems is therefore of general interest in order to gain a deeper understanding of the underlying principles. In this approach we try to separate the dynamics in time according to dominant interaction Hamiltonians. Being the canonical example in atomic physics, we apply this scheme to the classical dynamics of the helium atom [1].
