Abstract: In this analysis, we study the dynamics of quantum oscillator fields within the context of a position-dependent mass (PDM) system situated in an Einstein-Maxwell space-time, incorporating a non-zero cosmological constant. The magnetic field is aligned along the symmetry axis direction. To analyze PDM quantum oscillator fields, we introduce a modification to the Klein-Gordon equation by substituting the four-momentum vector $p_{mu} to Big(p_{mu}+i,eta,X_{mu}+i,mathcal{F}_{mu}Big)$ into the Klein-Gordon equation, where the four-vector is defibed by $X_{mu}=(0, r, 0, 0)$, $mathcal{F}_{mu}=(0, mathcal{F}_r, 0, 0)$ with $mathcal{F}_r=frac{f'(r)}{4,f(r)}$, and $eta$ is the mass oscillator frequency. The radial wave equation for the relativistic modified Klein-Gordon equation is derived and subsequently solved for two distinct cases: (i) $f(r)=e^{frac{1}{2},alpha,r^2}$, and (ii) $f(r)=r^{beta}$, where $alpha geq 0, beta geq 0$. The resultant energy levels and wave functions for quantum oscillator fields are demonstrated to be influenced by both the cosmological constant and the geometrical topology parameter which breaks the degeneracy of the energy spectrum. Furthermore, we observed noteworthy modifications in the energy levels and wave functions when compared to the results derived in the flat space background.
Analysis of Quantum Oscillator Fields with Position-Dependent Mass
In this analysis, we examine the dynamics of quantum oscillator fields within the context of a position-dependent mass (PDM) system situated in an Einstein-Maxwell space-time, incorporating a non-zero cosmological constant. The magnetic field is aligned along the symmetry axis direction.
To analyze PDM quantum oscillator fields, we introduce a modification to the Klein-Gordon equation by substituting the four-momentum vector pμ → (pμ + iηXμ+ i𝓕μ) into the Klein-Gordon equation. Here, the four-vector is defined by Xμ = (0, r, 0, 0), 𝓕μ = (0, 𝓕r, 0, 0) with 𝓕r=f'(r) / (4f(r)), and η is the mass oscillator frequency.
Derivation and Solutions
The radial wave equation for the relativistic modified Klein-Gordon equation is derived and subsequently solved for two distinct cases:
- f(r) = e(1/2)αr²
- f(r) = rβ
In case (i), where f(r) = e(1/2)αr², and in case (ii), where f(r) = rβ, with α ≥ 0 and β ≥ 0, we obtain the resultant energy levels and wave functions for the quantum oscillator fields.
Influence of Cosmological Constant and Geometrical Topology Parameter
The energy levels and wave functions for quantum oscillator fields are demonstrated to be influenced by both the cosmological constant and the geometrical topology parameter, which breaks the degeneracy of the energy spectrum. Notably, there are modifications observed in the energy levels and wave functions when compared to the results derived in a flat space background.
