Magnetic and quadrupolar order in a one-dimensional ferromagnet with cubic crystal-field anisotropy
M. Dudzinski, G. Fath, J. Sznajd
The zero temperature phase diagram of a one-dimensional S=2 Heisenberg ferromagnet with single-ion cubic anisotropy is studied numerically using the density-matrix renormalization…

On the accuracy of the density matrix renormalization group method
Ors Legeza, Gabor Fath
White's density matrix renormalization group ({DMRG}) method has been applied to the one-dimensional Ising model in a transverse field ({ITF}), in order to study the accuracy of th…

Solitonic excitations in the Haldane phase of a S=1 chain
G. Fath, J. Solyom
We study low-lying excitations in the 1D antiferromagnetic valence-bond-solid (VBS) model. In a numerical calculation on finite systems the lowest excitations are found to fo…
