Phases of the frustrated XY model on the honeycomb lattice

ORAL

Abstract

We study the phase diagram of the frustrated XY model on the honeycomb lattice by using accurate correlated wave functions and variational Monte Carlo simulations. Our results suggest that a spin-liquid state is energetically favorable in the region of intermediate frustration, intervening between two magnetically ordered phases. We briefly discuss our results in the light of recent DMRG simulations where instead of a spin liquid, an unsual magnetically ordered state is found.
