a The dynamics of participation entropy for the system quenched into the three phases. The yellow, red, and purple points are experimental data for the extended (μ = 0.5, V = 1.0), critical (μ = 2.0, V = 1.0), and localized (μ = 0.5, V = 4.0) phases, respectively. The dynamics of participation entropy with (b) fixed μ = 0.5 and varying V = 1 to 4, and (c) fixed V = 1 and varying μ = 0.5 to 2. Lines with the same color as points are numerical simulation under the same parameters with decoherence taken into account. Error bars represent the standard deviation.
