Time evolution of the generalized excess free energy for a characteristic time τ = γ / κ = 0.1844(3) ms, T c / T w = 0.11(1) and T h / T w = 3.56(1) for the backward protocol. Red circles stand for heating and blue squares stand for cooling. Solid lines correspond to the theoretical predictions without fitting parameters. Insets represent the initial value of the relative entropy D i w (0)/ k B T w ( y axis) as a function of the temperature ( x axis) on the logarithmic scale. The arrows represent the evolution direction along the master curve f(ρ )=(ρ -1-ln ρ )/2 . The data are estimated as the mean over ten independent measurements, whereas error bars are the s.e.m. (see Methods for further details).
