Spin liquid and strip solid phases in the extended XXZ model on the Kagome lattice

Employing large-scale quantum Monte Carlo simulations, we investigate the ground state phase diagram of an extended XXZ model on kagome lattice focusing on the magnetization at $m=1/6$. As the spin exchange interactions are reduced towards the Ising limit, the system undergoes a first order phase transition from ferromagnetic ordered phase to a strip solid phase that only breaks the lattice rotational symmetry. Further reducing the transverse interaction, a $Z_2$ spin liquid phase emerges. We introduce an additional fourth-neighbor interaction that allows to tune transitions between strip solid and spin liquid. The properties of the phase transitions are investigated.
