Density-matrix spectra for integrable models
I. Peschel, M. Kaulke, Ö. Legeza
The spectra which occur in numerical density-matrix renormalization group (DMRG) calculations for quantum chains can be obtained analytically for integrable models via corner trans…
Stability of the Haldane phase in anisotropic magnetic ladders
Ors Legeza, Jeno Solyom
We have considered the properties of anisotropic two-leg ladder models with S=1/2 or S=1 spins on the rungs, using White's density matrix renormalization group method. We have gene…
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…
The phase diagram of magnetic ladders constructed from a composite-spin model
Ors Legeza, Gabor Fath, Jeno Solyom
White's density matrix renormalization group ({DMRG}) method has been applied to an composite-spin model, which can also be considered as a two-leg ladder model. By…
