| Abstract | Large symmetry groups in quantum many-body systems could strongly enhance quantum fluctuations and thereby stabilize exotic quantum phases. Frustrated interactions were long known to have similar effects. Here we intertwine the large SU(N) symmetry and the frustration in a J1−J2SU(N) Heisenberg model on a honeycomb lattice, where J1 is the nearest-neighbor coupling and J2 is the next-nearest-neighbor coupling. With a large-N analysis, we obtain a rich phase diagram by varying both N and the ratio J2/J1. The ground states include Dirac spin liquid, chiral spin liquid, valence cluster solids, flux ordered state, and stripe states. The physical properties of each phase are discussed. |
