  • Overcoming reciprocity is important for novel functionalities. Here, the authors demonstrate a spatio-temporally modulated metasurface capable of complete violation of Lorentz reciprocity by reflecting an incident beam into far-field radiation in forward scattering, but into near-field surface waves in reverse scattering.

  • The Casimir force is a ubiquitous interaction arising from electromagnetic quantum fluctuations. Here, the authors uncover the underlying physics governing Casimir force phase transitions in staggered 2D materials in the graphene family.

  • The dynamical Casimir effect — the generation of photons out of the quantum vacuum induced by an accelerated body — has been experimentally demonstrated using a superconducting circuit that simulates a moving mirror. See Letter p.376

  • The Casimir force between two objects in close distance to each other can be an important yet undesirable force for nanoscale devices. Here, Intravaia et al. observe that nanostructured metal surfaces show a Casimir force that is reduced even further than suggested by existing theoretical models.

  • The Casimir torque, a quantum effect caused by the vacuum and thermal fluctuations of the electromagnetic field, is a phenomenon that can cause friction, but is also a manifestation of the optical angular momentum of light. This work describes the transfer of angular momentum between spinning nanoparticles enabled by the Casimir torque and provides calculations for the rotational dynamics of the system.
