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, ...

When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules ...

Quantum spin chains constitute a class of one‐dimensional quantum systems where spins interact via nearest-neighbour or longer-range couplings. These models have long served as paradigms for ...

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 ...

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 ...

In these chains, the magnetic moments align in an antiparallel manner but do not completely cancel out. Also of great interest are two-dimensional spin lattices, which exhibit a much greater variety ...
