Regularizing free-scalar and Yang-Lee 5d CFTs on the fuzzy four sphere

Include the Julia code used in the paper: Ising_spectrum_ED: Compute Ising low lying spectrum on fuzzy S4, by exact diagonalization(ED). Yang_Lee_spectrum_ED: Compute Yang--Lee low lying spectrum on fuzzy S4, by ED. phase_trans: compute the energy level E_n vs hx for Ising phase transition, and E_n vs hz for Yang--Lee model Ising_optimize, Yang_Lee_optimize: obtain the critical point from minimizing the conformal cost, at I=2. YL_DMRG: include the DMRG computation, pseudo-orthogonal projection, and optimization of Yang_Lee model at I=3, computation of low lying spectrum Julia 1.10.3 is preferred, please cite the paper and FuzzfiED https://arxiv.org/abs/2503.00100 if used the code.
