Boson correlation functions for different β and μ. Solid lines are simulation results. Points are experimental data obtained by averaging over eight random samples. In a there is no significant difference of boson correlation functions between the μ = ±5 cases. However, this difference grows as the temperature (T = 1/β) goes down, as shown in b. At low temperature of c, the decay behavior of boson correlations for μ = −5 becomes similar with the case of μ = 0. For μ = 0, the pure SYK model at low temperature describes a maximally chaotic NFL phase with the fastest decay rate of boson correlation. While for μ = 5, the boson correlation decays much slower and saturates to a relatively large value, which corresponds to a spontaneous \({\cal{T}}\)-breaking phase
