A new study Physical Review X by Alexander Wietek MPI-PKS Dresden and collaborators reveals a surprising relation between quantum electrodynamics (QED) and frustrated magnets: QED describes not only electrons and photons but also highly frustrated triangular antiferromagnets.

A new mechanism to enhance the Nernst effect - wherein heat flow in a solid is converted to voltage - via magnetic fluctuations may lead to new applications in energy-harvesting devices.

In some topological states of matter, a surface-bulk connection called spectral flow underpins many of the material’s unusual properties. A new analysis, however, shows that most 3D topological phases do not actually possess spectral flow.
