Homework Statement: relation between qft and statistical physics
Homework Equations: domains with equal values
I read a french paper about Kenneth Wilson.
i translate several sentences (with google):
it was demonstrated in 1960 by Kenneth Wilson that renormalization formed an incongruous bridge between statistical physics and quantum field theory.
He connected the behavior of a system during a transition second-order phase to the behavior of a QFT field. More specifically, during the second-order phase transition, two phases of matter overlap, which leads to
scale invariance at the critical point.
My question is about this overlapping. the french word is "superpose"
How can phases overlap or be superposed? superposition is used in qft but here what does it mean?
