Generalized Zero-Temperature Glauber Dynamics in a Two-Dimensional Square Lattice

A new spin flipping mechanism at zero-temperature is proposed based on a node model. In a two-dimensional square lattice, at the zero-temperature, the spin flipping depends on both itself and the surroundings, while the influence from the surroundings is embodied by an adjustable parameter. With the parameter adjusting, a first order phase transition is observed.
