Square lattice gases with two- and three-body interactions revisited: a row-shifted (2x2) phase.
Monte Carlo simulations have been used to study the phase diagrams for square Ising-lattice-gas models with two- and three-body interactions for values of interaction parameters in a range that has not been previously considered. We find unexpected qualitative differences as compared with predictions made on general grounds.
