Abstract
The ground state properties and neutron structure factor for the two-dimensional antiferromagnet on the triangular lattice, with unidirectional anisotropy in the nearest-neighbor exchange couplings and a weak Dzyaloshinskii-Moriya (DM) interaction, are studied. This Hamiltonian has been used to interpret neutron scattering measurements on the spin $1∕2$ spiral spin-density-wave system, ${\mathrm{Cs}}_{2}{\mathrm{CuCl}}_{4}$ [R. Coldea et al., Phys. Rev. B 68, 134424 (2003)]. Calculations are performed using a $1∕S$ expansion, taking into account interactions between spin waves. The ground state energy, the shift of the ordering wave vector, $\mathbf{Q}$, and the local magnetization are all calculated to order $1∕{S}^{2}$. The neutron structure factor, obtained using anharmonic spin-wave Green's functions to order $1∕S$, is shown to be in reasonable agreement with published neutron data, provided that slightly different parameters are used for the exchange and DM interactions than those inferred from measurements in high magnetic field.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
