DMRG study of ferromagnetism in a one-dimensional Hubbard model
S. Daul, R. Noack
The one dimensional Hubbard model with nearest and (negative) next-nearest neighbour hopping has been studied with the density-matrix renormalization group (DMRG) method. A large r…

Variationnal study of ferromagnetism in the t1-t2 Hubbard chain
S. Daul, P. Pieri, M. Dzierzawa +2
A one-dimensional Hubbard model with nearest and (negative) next-nearest neighbour hopping is studied variationally. This allows to exclude saturated ferromagnetism for .…
