Left: the decay of rms temperature fluctuation (with anomalous suppression and no radiative cooling) with time normalized by classical conduction rate. Solid lines represent simulations and dashed lines show exponential decay. Different colors demonstrate different ε = β_e0λ_e0/ℓ_T,∥0. Right: comparison of the temperature profiles (normalized to initial mean temperature) for anomalous (blue) and classical (red) with ε = 36.4.
