A toolbox for quantum research: Empa researchers realize quantum spin models with nanographs

Molecular Lego Stones: For the homogeneous Heisenberg chain, the researchers used the nanograph molecule Olympic, which consists of five carbon rings. Image: Empa DMZ – SCIENCE ¦ MM ¦ AA ¦ Dübendorf, St. Gallen and Thun – researchers from the Swiss Federal Institute for Materials Testing and Research (Empa) have experimented with an important theoretical model from quantum physics. The model is based on the work of the Nobel Prize winner in Phys…
