Abstract:We study the revival of Hofstadter butterfly due to the competition between disorder and elec- tronic interaction using mean field approximation of unrestricted Hartree Fock method at zero tem- perature for two dimensional square and honeycomb lattices. Interplay of disorder and electronic correlation to nullify each other is corroborated by the fact that honeycomb lattice needs more strength of electronic correlation owing to its less co-ordination number which enhances the effect of disorder. The extent of r… Show more
