Welcome to ct.qmat

With the help of a novel algorithm, magnetic topological compounds can now be searched for automatically. The computer method developed is considered a milestone for research into topological materials and paves the way for systematic identification of such materials, which have so far only been determined on a case-by-case basis.

Researchers of the Cluster of Excellence ct.qmat have proposed a new quantum material in which electrons move as a viscous fluid–like a kind of quantum honey. If scientists succeed in producing the material in sufficient purity, the effect will be three times stronger than in the “miracle material” graphene.

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.
