Mathematical aspects of intertwining operators: the role of Riesz bases
In this paper we continue our analysis of intertwining relations for both
self-adjoint and not self-adjoint operators. In particular, in this last
situation, we discuss the connection with pseudo-hermitian quantum mechanics
and the role of Riesz bases.Comment: Journal of Physics A, in pres
Vector coherent states and intertwining operators
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 of constructing non-isospectral hamiltonians with
related eigenstates
Coherent and Squeezed States: Introductory Review of Basic Notions, Properties, and Generalizations
A short review of the main properties of coherent and squeezed states is
given in introductory form. The efforts are addressed to clarify concepts and
notions, including some passages of the history of science, with the aim of
facilitating the subject for nonspecialists. In this sense, the present work is
intended to be complementary to other papers of the same nature and subject in
current circulation.Comment: 50 pages, misprints corrected, some new references included. To
