SUMMARY

The discussion centers on finding the steady-state concentration, c0(x), for N particles diffusing in one dimension under the potential U(x) = ax^2, where a > 0. The solution involves applying Fick's laws of diffusion and the Boltzmann distribution to derive the concentration profile. Key equations include the diffusion equation and the relationship between potential energy and concentration. The participants express confusion regarding the derivation process, indicating a need for clearer explanations of the underlying principles.

PREREQUISITES

N particles diffuse in one dimension in the potential U(x) = ax^2, with a > 0.
Find steady-state concentration, c0(x).

No idea how to solve this. Any equations?
