DMRG study of ferromagnetism in a one-dimensional Hubbard model

S. Daul, R. M. Noack

The one dimensional Hubbard model with nearest and (negative) next-nearest neighbour hopping has been studied with the densitymatrix renormalization group (DMRG) method. A large region of ferromagnetism has been found for finite density and finite on-site interaction. PACS: 74.25.Ha, 75.10.Lp 1
