Webb12 apr. 2024 · The long search for insulating materials that possess low-energy quasiparticles carrying electron's quantum numbers except charge---inspired by the neutral spin-$1/2$ excitations, the so-called spinons, exhibited by Anderson's resonating-valence-bond state---seems to have reached a turning point after the discovery of several Mott … Webb25 nov. 2013 · Particularly the mechanisms leading to the experimentally observed insulating ground states are investigated. These are found to be caused by the strong spin-orbit and Coulomb interactions of the $5f$ orbitals; however, as a result of the different configurations, this mechanism works in distinctly different ways for each of the …
