Variational study of the ground state and spin dynamics of the spin- $\frac{1}{2}$ Kagome antiferromagnetic Heisenberg model and its implication on Hebertsmithite ZnCu $_{3}$ (OH) $_{6}$ Cl $_{2}$

Chun Zhang, Tao Li

We find that the best RVB state of the spin- $\frac{1}{2}$ Kagome antiferromagnetic Heisenberg model(spin- $\frac{1}{2}$ KAFH) is described by a $Z_{2}$ gapped mean field ansatz, whi…

Theory of the anomalous spin dynamics of spin- $\frac{1}{2}$ triangular lattice Heisenberg antiferromagnet and its application to Ba $_{3}$ CoSb $_{2}$ O $_{9}$

Chun Zhang, Tao Li

Although it is well accepted that the spin- $\frac{1}{2}$ triangular lattice Heisenberg antiferromagnet(TLHAF) has a long range ordered ground state, a thorough understanding of its…
