Figure 4.

Steady-state membrane temperature depends on the collision angle and timestep. Three data series are shown using direct coupling: τ_MD = 2 fs with collisions every 50 steps (red circles) and every 10 steps (blue squares), and τ_MD = 20 fs with collisions every step (green triangles). SRD parameters for these data are a = 2.0 nm, and N = 1 nm⁻³. In addition, one data series is shown for the CC scheme (magenta diamonds) with τ_MD = 10 fs, a = 2.0 nm, collisions every 20 steps, and N = 2.4 nm⁻³. See Fig. S2 for the membrane temperature as a function of τ_MD and τ_C for the CC scheme. To see this figure in color, go online.
