This article lists the critical exponents of the ferromagnetic transition in the Ising model.
In statistical physics, the Ising model is the simplest system exhibiting a continuous phase transition with a scalar order parameter and
The critical exponents of the transition are universal values and characterize the singular properties of physical quantities.
The ferromagnetic transition of the Ising model establishes an important universality class, which contains a variety of phase transitions as different as ferromagnetism close to the Curie point and critical opalescence of liquid near its critical point.
From the quantum field theory point of view, the critical exponents can be expressed in terms of scaling dimensions of the local operators
of the conformal field theory describing the phase transition[1] (In the Ginzburg–Landau description, these are the operators normally called
Renormalization group methods,[9][10][11][12] Monte-Carlo simulations,[13] and the fuzzy sphere regulator[14] give results in agreement with the conformal bootstrap, but are several orders of magnitude less accurate.
Based on the numerical conformal bootstrap results, Ning Su conjectured in 2019 that
