Regulated perturbation theory for two-dimensional atomic systems

We have developed a novel approach called regulated perturbation theory for solving the Schrodinger equation of a two-dimensional hydrogen atom in an external field by combining the conventional perturbation method with several elements of the Feranchuk-Komarov method. This includes the Levi-Civita transformation, the algebraic calculation technique using the annihilation and creation operators, and the introduction of a free parameter to optimize the convergence rate of the perturbation series. The application is demonstrated for excitons in monolayer transition-metal dichalcogenides in a magnetic field.
