Abstract. Some examples of branched Hamiltonians are explored, as advocated by Shapere and Wilczek. These are actually cases of switchback potentials, albeit in momentum space, as previously analyzed for quasi-Hamiltonian dynamical systems in a classical context. A basic model, with a pair of Hamiltonian branches related by supersymmetry, is considered as an interesting illustration.
