Welcome to the website of the Quantum Matter Theory Group at the Lorentz Institute, Leiden University. Our research revolves around macroscopic matter that is one or the other way still in the grip of quantum physics.
The group leader Jan Zaanen is suffering from cancer, when you are interested in his story see zaanenstory.

Electronic structure of the parent compound of superconducting infinite-layer nickelates The search continues for nickel oxide-based materials with electronic properties similar to cuprate high-temperature superconductors 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The recent discovery of superconductivity in the doped infinite-layer nickelate NdNiO 2 (refs. 11, 12) has strengthened these efforts. Nature
Superconductivity theory under attack
Measurements on a superconducting material show an abrupt transition between a normal metal and a ‘strange’ metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. ‘We don’t have any theoretical machinery for this’, says theoretical physicist Jan Zaanen, co-author of a Science article, ‘this is something that only a quantum computer can calculate’.
