Article: A parametric approach to supersymmetric quantum mechanics in the solution of Schrödinger equation
[Show abstract] [Hide abstract]
ABSTRACT: We study exact solutions of the Schrödinger equation for some potentials. We introduce a parametric approach to supersymmetric quantum mechanics to calculate energy eigenvalues and corresponding wave functions exactly. As an application we solve Schrödinger equation for the generalized Morse potential, modified Hulthen potential, deformed RosenMorse potential and PoschlTeller potential. The method is simple and effective to get the results.Journal of Mathematical Physics 02/2014; 55(3). DOI:10.1063/1.4866979 · 1.24 Impact Factor  [Show abstract] [Hide abstract]
ABSTRACT: In this work, we study the Dirac equation with scalar, vector, and tensor interactions. The Dirac Hamiltonian contains quadratic scalar and vector potentials, as well as a tensor potential. The tensor potential is taken as a sum of a linear term and a Coulomblike term. It is shown that the tensor potential preserves the form of the harmonic oscillator potential and generates spinorbit terms. The energy eigenvalues and the corresponding eigenfunctions are obtained for different alternatives.International Journal of Modern Physics C 05/2012; 20(06).

ABSTRACT: The Dirac equation, with positiondependent mass, is solved approximately for the generalized Hulthén potential with any spinorbit quantum number κ. Solutions are obtained by using an appropriate coordinate transformation, reducing the effective mass Dirac equation to a Schrödingerlike differential equation. The NikiforovUvarov method is used in the calculations to obtain energy eigenvalues and the corresponding wave functions. Numerical results are compared with those given in the literature. Analytical results are also obtained for the case of constant mass and the results are in good agreement with the literature.

ABSTRACT: The Dirac–Morse problem is investigated within the framework of an approximation to the term proportional to 1/r2 in the view of the positiondependent mass formalism. The energy eigenvalues and corresponding wave functions are obtained by using the parametric generalization of the Nikiforov–Uvarov method for any κvalue.
