In the paper, a new nonrelativistic analytical model is presented and used to modify the Schrödinger equation for atomic scales with two dimensional modified Killingbeck potential (2DMKBP) for the hydrogenic atoms and quarkonium system in noncommutative two-dimensional real space-phase (NC: 2D-RSP). We applied the generalized Bopp’s shift method to obtain 2DMKBP involving ordinary 2D-Killingbeck potential (2DKBP) and some central terms proportional to the two infinitesimals parameters EMBED Equation.DSMT4 . We have also observed the new kinetic term composed of ordinary kinetic term and additive part proportional to infinitesimals parameter EMBED Equation.DSMT4 . Furthermore, the global Hamiltonian operator for 2DMKBP involves three fundamental parts: the first one is the ordinary Hamiltonian operator in commutative quantum mechanics (CQM), the second part is the spin-orbit operator EMBED Equation.DSMT4 , while the third is the modified Zeeman operator EMBED Equation.DSMT4 . Thus, the global energy will include in addition to the ordinary energy in CQM two principal corrections ( EMBED Equation.DSMT4 , EMBED Equation.DSMT4 ) and EMBED Equation.DSMT4 corresponding to the spin-orbit interaction and modified Zeeman effect, respectively. The global energy levels EMBED Equation.DSMT4 depend on discrete atomic quantum numbers EMBED Equation.DSMT4 and the parameters of studied potential EMBED Equation.DSMT4 . Moreover, we have generalized the obtained results to include the quarkonium system ( EMBED Equation.DSMT4 and EMBED Equation.DSMT4 ). We have also shown that the mass spectra of quarkonium system were changed to the new forms. The previous results in CQM become special cases when we make the simultaneously two limits EMBED Equation.DSMT4 . |
