Coherent states associated with tridiagonal Hamiltonians
Hashim A. Yamani, Zouhaïr Mouayn
It has been shown that a positive semi-definite Hamiltonian H, that has a tridiagonal matrix representation in a given basis, can be represented in the form H = A†A, where A is a f…

Husmi Q-functions attached to hyperbolic Landau levels
Z. Mouayn, H. Chhaiba, H. Kassogue +1
We are concerned with a phase-space probability distribution which is known as Husimi -function of a density operator with respect to a set of coherent states $\vert\widetildeκ_…

A set of -coherent states for the Rogers-Szegő oscillator
Othmane El Moize, Zouhaïr Mouayn
We discuss a model of a -harmonic oscillator based on Rogers-Szegő functions. We combine these functions with a class of -analogs of complex Hermite polynomials to construct…
