Fig. 4: Thermophoresis as selection in space for a three-state two-box model.

Difference between the probability of being in each box, ΔP = P2 − P1, as a function of dB/dA (in log-scale), for dC = dB/5 (blue curves) and dC = 5dB (vermilion curves). Different values of the gradient ΔT are shown. When ΔP is positive, the particles (independently of the species) accumulate on the cold side (blue/right box), and the Soret coefficient ST is positive. On the contrary, the particles are more abundant in the warm side (red/left box) for negative ΔP, corresponding to negative values of ST. In this example, we set Tm = 0.7, ΔE = 0.1, Δϵ = 2 and, dA = 0.01. kB has been taken equal to 1 for simplicity.
