Dirac systems with magnetic field and position dependent mass: Darboux transformations and equivalence with generalized Dirac oscillators
Axel Schulze-Halberg, Pinaki Roy
We construct a Darboux transformation for a class of two-dimensional Dirac systems at zero energy. Our starting equation features a position-dependent mass, a matrix potential, and…
Darboux partners of Heun-class potentials for the two-dimensional massless Dirac equation
A. Schulze-Halberg, A. M. Ishkhanyan
We apply the Darboux transformation to construct new exactly-solvable cases of the two-dimensional massless Dirac equation for potential classes of Lambert-W and inverse exponentia…
Exactly-solvable quantum systems in terms of Lambert-W functions
A. Schulze-Halberg, A. M. Ishkhanyan
We construct a variety of new exactly-solvable quantum systems, the potentials of which are given in terms of Lambert-W functions. In particular, we generate Schrödinger models wit…
Bound states of the two-dimensional Dirac equation for an energy-dependent hyperbolic Scarf potential
A. Schulze-Halberg, P. Roy
We study the two-dimensional massless Dirac equation for a potential that is allowed to depend on the energy and on one of the spatial variables. After determining a modified ortho…
