Intra- and interstate interactions in Anderson-localised states

摘要: In order to investigate the interplay of randomness and electron correlation in Anderson-localised states, a general theoretical model which treats electron-electron interaction between these states is presented. constructing Hamiltonian, behaviour localised with envelope functions explicitly taken into account. The spin susceptibility electronic specific heat as well density are calculated for this model. It shown that intrastate gives rise occurrence singly occupied below Fermi energy EF results Curie-type at low temperatures. As consequence variation from state state, doubly becomes large near EF. also interactions different give kinetic exchange states.
