文摘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.
