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 ...

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 ...
