1212.1757 (Richard C. Brower et al.)

Radial Quantization for Conformal Field Theories on the Lattice    [PDF]

Richard C. Brower, George T. Fleming, Herbert Neuberger
We consider radial quantization for conformal quantum field theory with a lattice regulator. A Euclidean field theory on $\mathbb R^D$ is mapped to a cylindrical manifold, $\mathbb R\times \mathbb S^{D-1}$, whose length is logarithmic in scale separation. To test the approach, we apply this to the 3D Ising model and compute $\eta$ for the first $Z_2$ odd primary operator.
