Axionic Casimir Torque
Abstract
In the canonical Casimir effect, the quantum vacuum is isotropic, and the minimization of vacuum energy drives only a linear attractive force between the plates. However, the introduction of an axion gradient breaks this rotational symmetry. It can be demonstrated that these asymmetric zero-point fluctuations exert a macroscopic mechanical twist on the plates proportional to b⃗2 sin (2ϑ) where b⃗ is the spatial axion gradient and ϑ is the angle between the axion gradient and the normal to the plates.
