Critical Coupling for Two-dimensional Theory in Discretized Light-Cone Quantization
arXiv:2109.13372 · doi:10.1103/PhysRevD.105.016020
Abstract
We solve for the critical coupling in the symmetric phase of two-dimensional field theory using Discretized Light-Cone Quantization. We adopt periodic boundary conditions, neglect the zero mode, and obtain a critical coupling consistent with the critical coupling reported using conformal truncation in light-front quantization. We find a 17% dfference from the critical coupling reported with light-front quantization in a symmetric polynomial basis.
