RG flow from ϕ⁴ theory to the 2D Ising model
We study 1+1 dimensional ϕ⁴ theory using the recently proposed method of conformal truncation. Starting in the UV CFT of free field theory, we construct a complete basis of states with definite conformal Casimir, C. We use these states to express the Hamiltonian of the full interacting theory in lig...
