Spin dynamics of the quasi-two-dimensional spin-1/2 quantum magnet Cs2CuCl4

Abstract:

We study dynamical properties of the anisotropic triangular quantum antiferromagnet Cs2CuCl4. Inelastic neutron scattering measurements have established that the dynamical spin correlations cannot be understood within a linear spin wave analysis. We go beyond linear spin wave theory by taking interactions between magnons into account in a 1S expansion. We determine the dynamical structure factor and carry out extensive comparisons with experimental data. We find that compared to linear spin w...
