When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules like beads on a string and let quantum mechanics take over. Put magnetic ...

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 ...

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 ...
