On the bound-state solutions of the Manning-Rosen potential including improved approximation to the orbital centrifugal term

open access: yes, 2011
The approximate analytical bound state solution of the Schr\"odinger equation for the Manning-Rosen potential is carried out by taking a new approximation scheme to the orbital centrifugal term. The Nikiforov-Uvarov method is used in the calculations. We

Transition to sub-Planck structures through the superposition of q-oscillator stationary states [PDF]

open access: yes, 2010
We investigate the superposition of four different quantum states based on the q-oscillator. These quantum states are expressed by means of Rogers-Szego polynomials.

New solutions of Heun general equation

open access: yes, 2009
We show that in four particular cases the derivative of the solution of Heun general equation can be expressed in terms of a solution to another Heun equation.

A Brief note on the Riemann hypothesis [PDF]

open access: yes, 2011
We deal with the Euler's alternating series of the Riemann zeta function to define a regularized ratio appeared in the functional equation even in the critical strip and show some evidence to indicate the hypothesis in this note.Comment: 4 pages; revised

Comment on `Solution of the Dirac equation for the Woods-Saxon potential with spin and pseudospin symmetry' [J. Y. Guo and Z-Q. Sheng, Phys. Lett. A 338 (2005) 90]

open access: yes, 2005
Out of the four bound-state solutions presented in loc. cit., only one (viz., the spin-symmetric one, in the low-mass regime) is shown compatible with the physical boundary conditions.

Unsuitable use of spin and pseudospin symmetries with a pseudoscalar Cornell potential

open access: yes, 2014
The concepts of spin and pseudospin symmetries has been used as mere rhetorics to decorate the pseudoscalar potential [Chin. Phys. B 22 090301 (2013)].

Uniform WKB approximation of Coulomb wave functions for arbitrary partial wave

open access: yes, 2008
Coulomb wave functions are difficult to compute numerically for extremely low energies, even with direct numerical integration. Hence, it is more convenient to use asymptotic formulas in this region.

Blow up solutions to a viscoelastic fluid system and a coupled Navier-Stokes/Phase-Field system in R^2

open access: yes, 2011
We find explicit solutions to both the Oldroyd-B model with infinite Weissenberg number and the coupled Navier-Stokes/Phase-Field system.
