Comment on ``Quantum mechanics of an electron in a homogeneous magnetic field and a singular magnetic flux tube''
R. M. Cavalcanti
Abstract
Recently Thienel [Ann. Phys. (N.Y.) 280 (2000), 140; quant-ph/9809047] investigated the Pauli equation for an electron moving in a plane under the influence of a perpendicular magnetic field which is the sum of a uniform field and a singular flux tube. Here we criticise his claim that one cannot properly solve this equation by treating the singular flux tube as the limiting case of a flux tube of finite size.
