The paper “Making sense of the divergent series for reconstructing a Hamiltonian from its eigenstates and eigenvalues“, co-authored by Carl Bender (Washington University), Dorje Brody, and Matthew Parry (University of Otago), has been published in the American Journal of Physics. The paper presents a method for summing divergent series of eigenstates of a Hamiltonian in quantum mechanics. A link to the AJP website is here, and a link to the arXiv version is here.
