Canonical coherent states can be written as infinite series in powers of a single complex number z and a positive integer ρ(m). The requirement that these states realize a resolution of the identity typically results in a moment problem, where the moments form the positive sequence of real numbers {ρ(m)} ∞ m=0. In this paper we obtain new classes of vector… (More)

The well-known canonical coherent states are expressed as an infinite series in powers of a complex number z together with a positive sequence of real numbers ρ(m) = m. In this article, in analogy with the canonical coherent states, we present a class of vector coherent states by replacing the complex variable z by a real Clifford matrix. We also present… (More)

Classes of coherent states are presented by replacing the labeling parameter z of Klauder-Perelomov type coherent states by confluent hyperge-ometric functions with specific parameters. Temporally stable coherent states for the isotonic oscillator Hamiltonian are presented and these states are identified as a particular case of the so-called Mittag-Leffler… (More)

A class of vector coherent states is derived with multiple of matrices as vectors in a Hilbert space, where the Hilbert space is taken to be the tensor product of several other Hilbert spaces. As examples vector coherent states with multiple of quaternions and octonions are given. The resulting generalized oscillator algebra is briefly discussed. Further,… (More)

Eigenfunctions and eigenvalues of the free magnetic Schrödinger operator , describing a spinless particle confined to an infinite layer of fixed width, are discussed in detail. The eigenfunctions are realized as an orthonormal basis of a suitable Hilbert space. Four different classes of temporally stable coherent states associated to the operator are… (More)

We present a class of vector coherent states in the domain D × D × .... × D (n-copies), where D is the complex unit disc, using a specific class of hermitian matrices. Further, as an example, we build vector coherent states in the unit disc by considering the unit disc as the homogeneous space of the group SU (1, 1).

The canonical coherent states were labeled by a single complex number z. In this article we present classes of coherent states labeled by some other choices, namely the iterates of a complex function, higher functions and elementary functions. Further, we show that some of these classes do not give the generalized oscillator algebra in the natural way.

The canonical coherent states are expressed as infinite series in powers of a complex number z in their infinite series version. In this article we present classes of coherent states by replacing this complex number z by other choices, namely, iterates of a complex function, higher functions and elementary functions. Further, we show that some of these… (More)
