Phase diagram of the Kitaev-Heisenberg model using various finite-size clusters

Masahiro Kadosawa, Masaaki Nakamura, Yukinori Ohta +1

We estimate phase boundaries of four ordered and two spin-liquid phases for the spin-$\frac{1}{2}$ Kitaev-Heisenberg (KH) model using four kinds of relatively-small clusters, based…
