Casimir torque and force on gratings
Résumé
We will discuss recent results: (i) on the theory of the Casimir torque between two gratings
rotated by an angle θ with respect to each other [1]; and (ii) on the theory and experiment
on the Casimir force between interpenetrating gratings [2]. These findings pave the way to
the design of contactless quantum vacuum torsional spring and sensors with possible
relevance to micro and nanomechanical devices.
