Vector coherent states and intertwining operators
F. Bagarello
Abstract
In this paper we discuss a general strategy to construct vector coherent states of the Gazeau-Klauder type and we use them to built up examples of isospectral hamiltonians. For that we use a general strategy recently proposed by the author and which extends well known facts on intertwining operators. We also discuss the possibility In a recent paper, [1], we have proposed a new procedure which gives rise, given few ingredients, to a hamiltonian h2 which has the same spectrum of a given hamiltonian h1 and whose respective eigenstates are related by a given intertwining operator. These results extend what was discussed in the previous literature on this subject, [2], and have
