Abstract

A generalisation of the discrete self-trapping (DST) Hamiltonian is presented. It is shown to be as good as the traditional one to study quantum ergodicity far from the uncoupled limit, while it is also suitable to be used in the near integrability regime, where the conventional DST Hamiltonian fails due to its non-genericity.
