The southern African endemic genus, Pachyphymus Uvarov, 1922 (Orthoptera: Acrididae: Euryphyminae), is the only genus in the Euryphyminae subfamily with enlarged and hump-shaped pronotal crests. Here, we redescribe two species using newly evaluated diagnostic characters: P. carinatus Dirsh, 1956 and P. cristulifer (Serville, 1838); and describe two new species: P. samwaysi n. sp. and P. namaque...

Exact solutions of Schrödinger equation are obtained for PT-/non-PT-symmetric and non-Hermitian generalized Woods−Saxon potential to get the complex-valued energy eigenvalues and the corresponding eigenfunctions for the bound states. NikiforovUvarov method is used in the calculations and generalized by means of the complex conjugate polynomials on the PT−symmetric quantum mechanics frame of ref...

The influence of temperature and a constant strong magnetic field on the quarkonium heavy meson spectrum is explored as result recent research suggesting that can be formed at primary stage in ultrarelativistic ion collisions (URHIC). Debye screen potential used non-relativistic models, states are termed charmonium & bottominum. In order to better understand current findings, comparison has...

We report bound-state solutions of the Klein–Gordon equation with a novel combined potential, Eckart plus class Yukawa by means parametric Nikiforov–Uvarov method. To deal centrifugal and coulombic behavior terms, we apply Greene–Aldrich approximation scheme. present any $$\ell$$ -state energy eigenvalues corresponding normalized wave functions mentioned system in closed form. discuss various s...

Abstract In this article, the linear plus modified Yukawa potential (LIMYP) is used as quark-antiquark interaction for approximate analytical bound state solution of Klein-Gordon equation in three-dimensional space. The energy eigenvalues and associated wavefunction are obtained by solving analytically using Nikiforov-Uvarov (NU) method. mass spectra heavy mesons such charmonium <?CDATA $(c\bar...
