Query: Phase diagram of the restricted solid-on-solid model coupled to the
  Ising model   We study the phase transitions of a restricted solid-on-solid model coupled
to an Ising model, which can be derived from the coupled XY-Ising model. There
are two kinds of phase transition lines. One is a Ising transition line and the
other is surface roughening transition line. The latter is a KT transition line
from the viewpoint of the XY model. Using a microcanonical Monte Carlo
technique, we obtain a very accurate two dimensional phase diagram. The two
transition lines are separate in all the parameter space we study. This result
is strong evidence that the fully frustrated XY model orders by two separate
transitions and that roughening and reconstruction transitions of crystal
surfaces occur separately.
