As part of an international collaboration, the group of Andrew Mackenzie have discovered manifestations of macroscopic quantum physics in ultrapure metals. These results have just been published in Science Magazine.
Physicists of the Cluster of Excellence ct.qmat have discovered spontaneous static magnetic fields with broken time-reversal symmetry in a class of iron-based superconductors. This exceptional property calls for new theoretical models and may become important in quantum computing. The research results have recently been published in the scientific journal Nature Physics.
