Figure 2. Work distribution ${ \mathcal P }(W)$ (red dashed curve) and the corresponding incoherent part ${{ \mathcal P }}_{+}(W)+{{ \mathcal P }}_{-}(W)$ (black solid curve) for (a) $t^{\prime} =0.01{\nu }_{0}^{-1}$, (b) $t^{\prime} ={\nu }_{0}^{-1}$ and (c) $t^{\prime} =100{\nu }_{0}^{-1}$. For panels (a) and (c), ${ \mathcal P }(W)$ and ${{ \mathcal P }}_{+}(W)+{{ \mathcal P }}_{-}(W)$ are coincident with each other. For all panels, ${\nu }_{t^{\prime} }=1.8{\nu }_{0}$, σ = ν0, $\beta =0.01{\nu }_{0}^{-1}$ and ν0 = 1.
