Soret effect
A temperature gradient in a mixture drives a concentration gradient as species migrate toward the hot or cold side. A thermal disequilibrium becomes a chemical one.

Relations
- a liquid mixture or solution under a steady temperature gradient
- the Soret and Dufour coefficients are Onsager-reciprocal
Matrix context
D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.
