Four PT-symmetric 1+1D quantum models are mapped to the Yang-Lee critical point via state-operator correspondence and bosonization, with scaling dimensions matching exact 2D results and a numerically confirmed growing two-point function.
Proposes and numerically tests a reconstructed Hamiltonian for approximate CFT ground states in any dimension that recovers CFT spectral properties.
