Energy dissipation suppresses phase diffusion and enhances phase sensitivity simultaneously. a, c Phase diffusion constant D and phase sensitivity χ are plotted against non-equilibrium parameter γ1 and γ2. b D depends inversely on energy dissipation per cycle ΔW. (inset) The envelope curve (dashed line), which shows the minimum phase diffusion constant, is fitted well by Dmin = C + W0/(ΔW − Wc)19. The fitting parameters are: Wc = 41.29, W0 = 36.44, and C = 0.2305. The volume of Gillespie simulation is V = 100. d χ exhibits linear dependence on ΔW and the maximum sensitivity χmax = KWΔW + const. with the proportional constant KW ≈ 6.5 × 10−3
