Energy and momentum eigenspectrum of the Hulthén-screened cosine Kratzer potential using proper quantization rule and SUSYQM method

Autor: Ajay Kumar Rai, Rajendrasinh H. Parmar, Kaushal R. Purohit

Publikováno v: Journal of Molecular Modeling. 27

Using the Qiang-Dong proper quantization rule (PQR) and the supersymmetric quantum mechanics approach, we obtained the eigenspectrum of the energy and momentum for time independent and time dependent Hulthen-screened cosine Kratzer potentials. For th

Construction of solvable non-central potential using vector superpotential: a new approach

Autor: Rajendrasinh H. Parmar

Publikováno v: Indian Journal of Physics. 93:1163-1170

We introduce here vector superpotential which is useful to find general potential form using supersymmetric quantum mechanics (SUSY QM) approach. Using the vector superpotential, we reconstruct different solved central potentials and non-central shap

Solution of the Ultra Generalized Exponential–Hyperbolic Potential in Multi-dimensional Space

Autor: Rajendrasinh H. Parmar

Publikováno v: Few-Body Systems. 61

In this work, we proposed ultra generalized exponential–hyperbolic potential (UGEHP) and derived various well known exponential–hyperbolic type potentials by setting parameters in UGEHP and using approximation suggested by Greene–Aldrich. The b

Rotational vibrational partition function using attractive radial potential plus class of Yukawa potential

Autor: Kaushal R. Purohit, Rajendrasinh H. Parmar, Ajay Kumar Rai

Publikováno v: AIP Conference Proceedings.

We determined the rotational vibrational (RV) partition function from the energy eigenvalues obtained for the attractive radial potential plus class of Yukawa potential (ARPCYP) via asymptotic iteration method (AIM). From these eigenvalue spectrum an

Approximate analytical solution of the extended Hulthen-Yukawa with inverse square and coulombic term plus ring shape potential

Autor: Kaushal R. Purohit, Rajendrasinh H. Parmar, Ajay Kumar Rai

Publikováno v: AIP Conference Proceedings.

In this study, we proposed and solved the extended Hulthen-Yukawa with inverse square and Coulombic term plus ring shape potential (EHYIC-RSP) via the Nikiforov-Uvarov (NU) method. Solution of the Schrodinger equation with the EHYIC-RSP obtained for

Generalized improved non-central potential and solution of Schrödinger equation with extended ring-shaped potential via Nikiforov-Uvarov method

Autor: Rajendrasinh H. Parmar

Publikováno v: The European Physical Journal Plus. 134

We propose a generalized improved non-central potential (GINCP) and reconstruct few ring-shaped and double-ring-shaped potentials earlier solved by different researchers. We construct an extended ring-shaped potential (ERSP). Using the Nikiforov-Uvar

Masses and decay constants of heavy$ndash$light flavour mesons in a variational scheme

Autor: P. C. Vinodkumar, Rajendrasinh H. Parmar, Ajay Kumar Rai

Publikováno v: Journal of Physics G: Nuclear and Particle Physics. 28:2275-2282

The hadronic properties of heavy–light flavour mesons, vis a vis B, Bs, D and Ds, are investigated by treating the light flavour relativistically and the heavy flavour non-relativistically with an effective quark–antiquark interaction potential o
