First-order phase transition in a driven lattice gas with nearest-neighbor exclusion
A lattice gas with infinite repulsion between particles separated by ≤ 1 lattice spacing, and nearest-neighbor hopping dynamics, is subjected to a drive that favors movement along the +x direction. The equilibrium (zero drive) transition to a phase with sublattice ordering, known to be continuous, turns discontinuous, and shifts to lower density with increasing bias. In the ordered nonequilibri...
متن کاملFirst- and second-order phase transitions in a driven lattice gas with nearest-neighbor exclusion.
A lattice gas with infinite repulsion between particles separated by < or = 1 lattice spacing, and nearest-neighbor hopping dynamics, is subject to a drive favoring movement along one axis of the square lattice. The equilibrium (zero drive) transition to a phase with sublattice ordering, known to be continuous, shifts to lower density, and becomes discontinuous for large bias. In the ordered no...
متن کاملPhase diagrams in the lattice restricted primitive model: from order-disorder to gas-liquid phase transition.
The phase behavior of the lattice restricted primitive model (RPM) for ionic systems with additional short-range nearest neighbor (NN) repulsive interactions has been studied by grand canonical Monte Carlo simulations. We obtain a rich phase behavior as the NN strength is varied. In particular, the phase diagram is very similar to that of the continuum RPM for high NN strength. Specifically, we...
متن کامل2 4 Ju n 19 99 Phase Diagram of the Lattice Restricted Primitive Model
We present a comprehensive study of the lattice restricted primitive model, i.e., a lattice gas consisting of an equal number of positively and negatively charged particles interacting via on-site exclusion and a 1/r potential. On the cubic lattice, Monte Carlo simulations show a line of Néel points separating a disordered, high-temperature phase from a phase with global antiferromagnetic order...
متن کاملCritical behavior of the restricted primitive model revisited
Reassessment of the critical temperature and density of the restricted primitive model of an ionic fluid by Monte Carlo simulations performed for system sizes with linear dimension up to L/σ = 34 and sampling of ∼ 10 9 trial moves leads to T * c = 0.04917 ± 0.00002 and ρ * c = 0.080 ± 0.005. Finite size scaling analysis based in the Bruce-Wilding procedure gives critical exponents in agreement ...
