Abstract:

The standard view of critical phenomena, such as the liquid-gas critical point

or the Curie temperature of a ferromagnet, is through the Renormalization Group.

I will describe an alternative – view it as a self-consistent “soup” of interacting

fluctuations, governed by tight equations of Conformal Field Theory.

This approach is both rigorous and calculable, with unprecedented precision

for the 3D Ising model critical exponents.
