Description

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. We calculate the cavity correction using a quantum mechanical formulation and demonstrate that it not only precisely matches the classical solution for a perfect cylinder but can also be generalized to allow for cavity imperfections.
