Amelino-Camelia DSR effects on charged Dirac oscillators: Modulated spinning magnetic vortices

Abstract

This work explores the two-dimensional Dirac oscillator (DO) within the framework of Amelino-Camelia doubly special relativity (DSR), employing a modified Dirac equation that preserves the first-order nature of the relativistic wave equation. By introducing non-minimal couplings, the system provides an exact analytical solution in terms of confluent hypergeometric functions, along with closed-form expressions for the energy spectrum (indulging a Landau-like signature along with accidental spin-degeneracies)-. In the low-energy limit, the results reproduce the well-known two-dimensional Dirac oscillator spectrum, and in the nonrelativistic regime, the results reduce the Schr & ouml;dinger oscillator spectrum. First-order corrections in this DSR model introduce a mass-splitting term proportional to +/-epsilon(degrees)/epsilon(p), where epsilon(degrees)=mc(2) is the rest energy and epsilon(p) is the Planck energy. These corrections preserve the symmetry between the energies of particles and antiparticles around zero energy, but induce a shift in the energy levels that becomes more significant for higher excited states (n>0). By mapping the system to a DSR-deformed charged Dirac oscillator in the presence of an out-of-plane uniform magnetic field, we show that the leading-order Planck-scale corrections vanish at a critical magnetic field B-0 (c), and as the magnetic field approaches this critical value, the relativistic energy levels approach E-n,E-+/- = +/-epsilon(degrees). Finally, we identify a previously undetermined feature in two-dimensional charged Dirac oscillator systems in a magnetic field, revealing that the corresponding modes manifest as spinning magnetic vortices.
