abstract = "Phase coherence and vortex order in the fully frustrated XY model
on a two-dimensional honeycomb lattice are studied by extensive
Monte Carlo simulations using the parallel tempering method and
finite-size scaling. No evidence is found for an equilibrium
order-disorder or a spin/vortex-glass transition, suggested in
previous simulation works. Instead, the scaling analysis of
correlations of phase and vortex variables in the full
equilibrated system is consistent with a phase transition where
the critical temperature vanishes and the correlation lengths
diverge as a power law with decreasing temperatures and
corresponding critical exponents nu(ph) and nu(upsilon).This
behavior and the near agreement of the critical exponents suggest
a zero-temperature transition scenario where phase and vortex
variables remain coupled on large length scales.",
