Exact diagonalization study of triangular Heisenberg model with four-spin ring-exchange interaction

Yuchao Zheng, Muwei Wu, Dao-Xin Yao +1

Using Lanczos exact diagonalization (ED), we study the spin-1/2 $J_{1}$ - $J_{2}$ Heisenberg model with the four-spin ring-exchange interaction $J_{r}$ on triangular lattice. We mainly use…
