Introduction to the conformal bootstrap and non-gaussianity of the critical 3d Ising model
Some critical indices of the 3D Ising are close to zero (eta), while others differ substantially from the free theory predictions. The conformal bootstrap provides the means to compute the critical indices. Moreover, one can get the four-point function, and its behavior shows the non-Gaussian nature of the critical point
