Russian physicists used the $O(2,1)$ algebraic framework to derive an integral representation for a 2D electron’s Green’s function in a magnetic monopole field, valid across the entire complex energy plane. The study employs operator methods, leveraging symmetry properties of the $O(2,1)$ algebra—a noncompact Lie algebra—to simplify calculations for electron-monopole interactions in reduced dimensions. This work extends theoretical tools for quantum systems in curved or topological fields, offering a unified approach to Green’s functions previously limited to specific energy regimes or spatial dimensions. Published in May 2026 on arXiv, the paper bridges quantum physics and mathematical physics, targeting researchers in monopole dynamics and algebraic quantum field theory. The findings may advance simulations of exotic quasiparticles in condensed matter systems, where effective monopole fields emerge in 2D materials like graphene or topological insulators.
