Zernike polynomials from the tridiagonalization of the radial harmonic oscillator in displaced Fock states

Hashim A. Yamani, Zouhaïr Mouayn

We revisit the J-matrix method for the one dimensional radial harmonic oscillator (RHO) and construct its tridiagonal matrix representation within an orthonormal basis phi(z)n of L…

Generalized coherent states for the harmonic oscillator by the J-matrix method with an extension to the Morse potential

Hashim A. Yamani, Zouhaïr Mouayn

While dealing with the J-Matrix method for the harmonic oscillator to write down its tridiagonal matrix representation in an orthonormal basis of L2(R); we rederive a set of genera…

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…

Coherent States of Systems with Pure Continuous Energy Spectra

Zouhair Mouayn, Hashim A. Yamani

While dealing with a Hamiltonian with continuous spectrum we use a tridiagonal method involving orthogonal polynomials to construct a set of coherent states obeying a Glauber-type…

Iterative polynomial-root-finding procedure with enhanced accuracy

Hashim A. Yamani, Abdulaziz D. Alhaidari

We devise a simple but remarkably accurate iterative routine for calculating the roots of a polynomial of any degree. We demonstrate that our results have significant improvement i…

Properties of shape-invariant tridiagonal Hamiltonians

Hashim A. Yamani, Zouhaïr Mouayn

It has been established that a positive semi-definite Hamiltonian,, that has a tridiagonal matrix representation in a basis set, allows a definition of forward (and backward) sh…

Supersymmetry of the Morse oscillator

Hashim A Yamani, Zouhair Mouayn

While dealing in [1] with the supersymmetry of a tridiagonal Hamiltonian H, we have proved that its partner Hamiltonian H(+) also have a tridiagonal matrix representation in the sa…

Extension and exact realization of the Heller's derivative rule

Hashim A. Yamani, Abdulaziz D. Alhaidari

The accuracy of the Heller's derivative rule to calculate the numerical weights associated with discretized energy spectrum is enhanced by Broad's extension which adds (N-1) more i…

J-matrix method of scattering in any L2 basis

H. A. Yamani, A. D. Alhaidari, M. S. Abdelmonem

The restriction imposed on the J-matrix method of using specific L2 bases is lifted without compromising any of the advantages that it offers. This opens the door to a wider range…
