Fig. 3: Dynamical evolutions of the entropy rates.
From: Entropy measurement of nonequilibrium phonon heat transport
a The entropy production rate Π, the entropy flux rate Φ, and the time variation of entropy dS/dt, and b Φ1,2 as a function of time for Λ/2π = 8 Hz. c Π, Φ, and dS/dt, and d Φ1,2 as a function of time for Λ/2π = 80 Hz. Each curve is averaged over 1000 trajectories. The effective temperatures of thermal reservoirs are the same as those of Fig. 2. The shaded regions represent the standard deviations. The solid curves are the theoretical simulations.
