Phys. … WebbMott insulators are a class of materials that are expected to conduct electricity according to conventional band theories, but turn out to be insulators (particularly at low temperatures). These insulators fail to be correctly described by band theories of solids due to their strong electron–electron interactions, which are not considered in …

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 … Webb15 dec. 2006 · An insulator has an energy gap separating filled and empty bands of electronic states, and thus is electrically inert because a finite energy is required to … WebbTHEORY OF THE INSULATING STATE 465 A series of more recent papers [9-14] has established Kohn’s pioneering viewpoint on a sound formal and computational basis, … dialog touchoutside
