Quantum Vacuum Energy Torque Anomoly

Fulling et al. have found an apparent violation of the relationship between torque and total vacuum energy based on the expectation values of the energy density and pressure of a quantum field inside a conducting wedge as a function of angle. The basic physics underlying the Casimir effect will be presented followed by a brief description of the eigenfunction expansions used to solve Casimir boundary value problems. Finally, details of the torque anomaly will be reviewed.
