Diffraction of the Aharonov-Bohm Hamiltonian

In this paper, we compute the diffractive wave propagator of the Aharonov-Bohm effect (Aharonov and Bohm, Phys Rev 115(3):485, 1959) on R-2 with a single solenoid using a technique of moving solenoid location. In addition, we compute the corresponding diffraction coefficient which is the principal symbol of the diffractive propagator. This paper proves the propagation of singularities of the Aharonov-Bohm Hamiltonian.
