In a new publication in Nature Materials, an international team of researchers has developed groundbreaking artificial chains of the iconic "olympicene" molecules to realize the antiferromagnetic (AF) ...

Scientists demonstrate for the second time that theoretical models of quantum physics can be realized with nanographenes, making their predictions experimentally testable. In the alternating model, ...

Frustrated quantum spin chains are one-dimensional systems in which competing interactions between adjacent and next-nearest-neighbour spins inhibit the establishment of conventional magnetic order.

The rapid progress of quantum simulators is now enabling them to study problems that before have been limited to the domain of theoretical physics and numerical simulation. A team of researchers at ...

Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful ...

For the homogeneous Heisenberg chain, the researchers used the nanographene molecule Olympicen, which consists of five carbon rings. In 2024, Empa researchers and their partners successfully for the ...
