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 - Heisenberg model with the four-spin ring-exchange interaction on triangular lattice. We mainly use…
