Consequences of lattice imperfections and interchain couplings for the critical properties of spin-1/2 chain compounds
To allow for a comparison of theoretical predictions for spin chains with experimental data, it is often important to take impurity effects as well as interchain couplings into account. Here we present the field theory for finite spin chains at finite temperature and calculate experimentally measura...

description | To allow for a comparison of theoretical predictions for spin chains with experimental data, it is often important to take impurity effects as well as interchain couplings into account. Here we present the field theory for finite spin chains at finite temperature and calculate experimentally measurable quantities like susceptibilities and nuclear magnetic resonance spectra. For the interchain couplings we concentrate on geometries relevant for cuprate spin chains like Sr<sub>2</sub>CuO<sub>3</sub> and SrCuO<sub>2</sub>. The field theoretical results are compared to experimental as well as numerical data obtained by the density matrix renormalization group. |
