- Abstract: We investigate the steady-state phase diagram of the dissipative spin-1/2 XYZ
model on a two-dimensional triangular lattice, in which each site is coupled to
a local environment. By means of cluster mean-field approximation, we find that
the steady-state phases of the system are rather rich, in particular there
exist various types of nonuniform antiferromagnetic phases due to the
geometrical frustration. As the short-range correlations included in the
analysis, the numerical results show that the oscillatory phase disappears
while the triantiferromagnetic and biantiferromagnetic phases remain to exist
in the thermodynamic limit. Moreover, the existence of the spin-density-wave
phase, which is missed by the single-site mean-field analysis, is also revealed
by the spin-structure factor.
