FIG. 2. Force-distance relation and distance fluctuations from theory and simulation.

FIG. 2

a) Without chemical activity, particles pushed together with force F (units of 2kBT/r0) entropically repel (solid line). 〈r〉 as a function of F is depressed for attractions in both the theory (dashed line) and simulation (solid circles). 〈r〉 is larger for repulsions in the theory (dash-dotted line) and simulation (open circles). Dotted line shows 〈r〉 = 2r0 and L = 30. b) The corresponding distance fluctuations.
