| Oct 24, 2018 at 13:21 | comment | added | Dimitri | @MichaelSeifert You are right, I should have added the depletion term to $\partial{\rho}/\partial{t}$, i.e. $\partial{\rho}/\partial{t} = D\nabla^2 \rho - k \rho$ at $x=0$ | |

| Oct 24, 2018 at 12:53 | comment | added | Michael Seifert | In eq (1), the right-hand side would be $D \nabla^2 \rho + k \nabla \cdot \rho$ at $x = 0$. Naïvely, this looks like you're adding a scalar to a vector. Can you clarify what you mean by editing the question? | |
