Complete phase diagram of the spin-1/2 $J_1$-$J_2$-$J_3$ model (with $J_3=J_2$) on the honeycomb lattice

Abstract

We use the coupled cluster method to investigate the ground-state (GS) properties of the frustrated spin-1/2 $J_1$-$J_2$-$J_3$ model on the honeycomb lattice, with nearest-neighbor exchange coupling $J_1$ plus next-nearest-neighbor ($J_2$) and next-next-nearest-neighbor ($J_3$) exchanges of equal strength. In particular we find a direct first-order phase transition between the Néel-ordered antiferromagnetic phase and the ferromagnetic phase at a value $J_2/J_1=-1.17\pm 0.01$ when $J_1>0$, compared to the corresponding classical value of -1. We find no evidence for any intermediate phase. From this and our previous CCM studies of the model we present its full zero-temperature GS phase diagram.
