Dynamical Correlations of Low Dimensional Quantum Magnets
The dynamical structure factor (DSF) is an important quantity in the characterization and understanding of quantum magnets, both experimentally and theoretically. In this thesis the DSF is calculated for three different spin-1/2 systems with reduced spatial dimensions. These are: the bond alternatin...

The dynamical structure factor (DSF) is an important quantity in the characterization and understanding of quantum magnets, both experimentally and theoretically. In this thesis the DSF is calculated for three different spin-1/2 systems with reduced spatial dimensions. These are: the bond alternating Heisenberg chain; the anisotropic Heisenberg, or XXZ, chain; and n a anisotropic triangular antiferromagnet with Dzyaloshinskii-Moriya interaction. All three cases are motivated by inelastic neutron scattering experiments on realistic manifestations of the models. |
