Our latest work enhancing the Casimir torque is published in Physical Review Letters

Quantum fluctuations of electromagnetic waves can result in a torque between two optically anisotropic materials. In David’s recent paper (entitled “Casimir-Lifshitz Torque Enhancement by Retardation and Intervening Dielectrics”), we show that a full calculation of this phenomenon taking into account the finite speed of light shows that the torque is stronger than expected and can be increased further with a dielectric spacer layer between the objects. This paper can be found in Phys. Rev. Lett. 119, 183001 (2017), and a press release can be found here.
