Abstract

In this paper we analyze the groundstate and finite-temperature properties of a frustrated Heisenberg $J_1-J_2$ model on a honeycomb lattice by employing the Schwinger boson technique. The phase diagram and spin gap as functions of ${J}_{2}/{J}_{1}$ are presented, showing that the exotic spin liquid phase lies in $0.21
