Query: Study of first-order interface localization-delocalization transition in
  thin Ising-films using Wang-Landau sampling   Using extensive Monte Carlo simulations, we study the interface localization-
delocalization transition of a thin Ising film with antisymmetric competing
walls for a set of parameters where the transition is strongly first-order.
This is achieved by estimating the density of states (DOS) of the model by
means of Wang-Landau sampling (WLS) in the space of energy, using both,
single-spin-flip as well as N-fold way updates. From the DOS we calculate
canonical averages related to the configurational energy, like the internal
energy, the specific heat, as well as the free energy and the entropy. By
sampling microcanonical averages during simulations we also compute
thermodynamic quantities related to magnetization like the reduced fourth order
cumulant of the order parameter. We estimate the triple temperatures of
infinitely large systems for three different film thicknesses via finite size
scaling of the positions of the maxima of the specific heat, the minima of the
cumulant and the equal weight criterion for the energy probability
distribution. The wetting temperature of the semi-infinite system is computed
with help of the Young equation. In the limit of large film thicknesses the
triple temperatures are seen to converge towards the wetting temperature of the
corresponding semi-infinite Ising model in accordance with standard capillary
wave theory. We discuss the slowing down of WLS in energy space as observed for
the larger film thicknesses and lateral linear dimensions. In case of WLS in
the space of total magnetization we find evidence that the slowing down is
reduced and can be attributed to persisting free energy barriers due to shape
transitions.
