Some properties of coherent states with singular complex matrix argument

Dušan Popov

In the paper our aim was to study the properties of a new version of coherent states whose argument is a linear combination of two special singular square 2 x 2 matrix, having a si…

Generalized coherent states with shifted (displaced) arguments

Dušan Popov

In the paper we developed a procedure for constructing generalized coherent states with shifted argument, as a result of the action of the generalized displacement operator. This w…

Four-parameter Mittag-Leffler functions and their associated coherent states

Dušan Popov

We defined and used a pair of Hermitian annihilation and creation operators which generate the generalized coherent states, defined in the Barut-Girardello manner, whose normalizat…

Some new considerations about the -function

Dušan Popov

The present paper starts from a previously deduced result, in which the -function plays the role of the normalization function of generalized hypergeometric coherent states for…

An application of the theta operator in generalized hypergeometric coherent states formalism

Dušan Popov

In this paper we examine one of the multiple applications of the theta operator xd/dx in quantum mechanics, namely, in the formalism of generalized hypergeometric coherent states (…
