Kavli Affiliate: Yi Zhou | First 5 Authors: Jin-Tao Jin, Yi Zhou, , , | Summary: We develop a comprehensive Ginzburg-Landau theory describing triple-Q magnetic orders on hexagonal lattices, focusing on $O(N)$ models with $N=2$ and $N=3$. Through systematic analysis of symmetry-allowed terms in the free energy, we establish complete phase diagrams governed by competing […]
