【 摘 要 】

We study the behavior of the depletion potential in binary mixtures of hard particles in one, two, and three dimensions within the framework of a general theory for depletion potential using density functional theory. By doing so we extend earlier studies of the depletion potential in three dimensions to the cases of 𝑑 = 1 and 2 about which little is known, despite their importance for experiments. We also verify scaling relations between depletion potentials in sphere–sphere and wall–sphere geometries in 𝑑 = 3 and in disk–disk and wall–disk geometries in 𝑑 = 2, which originate from geometrical considerations.
