Abstract: The anomalous magnetic dipole moment (g-2) of the electron is one of the most precisely measured quantities in the world. Experimentally, an electron is trapped in a cylindrical cavity, and the measured value of g-2 receives a correction due to the cavity boundary that must be subtracted off. To push precision further, we must account for imperfections in the cavity. I will demonstrate how to calculate the (classical) cavity correction using quantum methodologies that allow us to naturally generalize to the case of an imperfect cavity.
