Casimir torque and force on gratings
Résumé
We will discuss recent results: (i) on the Casimir torque between two metallic one-dimensional
gratings rotated by an angle θ with respect to each other; and (ii) on the Casimir force occurring between interpenetrating gratings. These findings pave the way to the design of a
contactless quantum vacuum torsional spring, and sensors with possible relevance to microand nanomechanical devices.
