Minimal model to describe the magnetism of
G. Bouzerar, O. Legeza, T. Ziman
We show that to describe properly the low energy excitations of one must include the effects of a transverse antiferromagnetic coupling, which is estimated to be $J_{\p…
A new model to describe the physics of VOPO
A. Weisse, G. Bouzerar, H. Fehske
In the past different models for the magnetic salt vanadyl pyrophosphate (VOPO) were discussed. Neither a spin ladder nor an alternating chain are capable to describe recently meas…
On the Incommensurate Phase in Modulated Heisenberg Chains
F. Schönfeld, G. Bouzerar, G. S. Uhrig +1
Using the density matrix renormalization group method (DMRG) we calculate the magnetization of frustrated S=1/2 Heisenberg chains for various modulation patterns of the nearest nei…
Elementary Excitations in Dimerized and Frustrated Heisenberg Chains
G. Bouzerar, A. P. Kampf, G. I. Japaridze
We present a detailed numerical analysis of the low energy excitation spectrum of a frustrated and dimerized spin Heisenberg chain. In particular, we show that in the comme…
Magnetic Excitations in the Spin-Peierls System
G. Bouzerar, A. P. Kampf, F. Schönfeld
We have calculated the magnetic excitation spectrum in frustrated and dimerized spin 1/2 Heisenberg chains for model parameters which describe the thermodynamics and low frequency…
