Charge-density waves in one-dimensional Hubbard superlattices

Thereza Paiva, Raimundo R. dos Santos

We study the formation of charge density waves (CDW's) in one-dimensional Hubbard superlattices, modeled by a repeated pattern of repulsive (U>0) and free (U=0) sites. By means of…

Hole concentration in a diluted ferromagnetic semiconductor

Raimundo R. dos Santos, Luiz E. Oliveira, J. d'Albuquerque e Castro

We consider a mean-field approach to the hole-mediated ferromagnetism in III-V Mn-based semiconductor compounds to discuss the dependence of the hole density on that of Mn sites in…
