Revisiting the dilatation operator of the Wilson–Fisher fixed point
We revisit the order-ε dilatation operator of the Wilson–Fisher fixed point obtained by Kehrein, Pismak, and Wegner in light of recent results in conformal field theory. Our approach is algebraic and based only on symmetry principles. The starting point of our analysis is that the first correction t...
