Binder parameter

From Wikipedia, the free encyclopedia

The Binder parameter or Binder cumulant[1][2] in statistical physics, also known as the fourth-order cumulant is defined as the kurtosis of the order parameter, s, introduced by Austrian theoretical physicist Kurt Binder. It is frequently used to determine accurately phase transition points in numerical simulations of various models. [3]

The phase transition point is usually identified comparing the behavior of as a function of the temperature for different values of the system size . The transition temperature is the unique point where the different curves cross in the thermodynamic limit. This behavior is based on the fact that in the critical region, , the Binder parameter behaves as , where .

Accordingly, the cumulant may also be used to identify the universality class of the transition by determining the value of the critical exponent of the correlation length. [1]

In the thermodynamic limit, at the critical point, the value of the Binder parameter depends on boundary conditions, the shape of the system, and anisotropy of correlations. [1][4][5][6]
