Researchers from the Faculty of Physics at the University of Warsaw and the University of British Columbia have described how a so-called lone spinon—an exotic quantum excitation that is a single ...

Potassium copper fluoride KCuF 3 is considered the simplest model material realising the so-called Heisenberg quantum spin chain: The spins interact with their neighbours antiferromagnetically ...

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 ...

It would be surprising if the spin-1⁄2 Heisenberg model were in this universality class, as conjectured by the researchers at Ljubljana, because it is linear and non-stochastic, ...

For the alternating spin chain model, the researchers used so-called Clar's goblets as their starting material, hourglass-shaped nanographene molecules consisting of eleven carbon rings. For the ...
