I am no specialist in noise terms, either, but the \delta(\vec{r} -
\vec{r}')\delta(t - t') terms express "uncorrelated in space and time", so both
\xi_c and \xi_\eta have that property in what you attached.
Equation (1a) with the Laplacian is the appropriate conservative form for the

Can you give a few more details on the problem with the boundary
condition? A lot of issues with boundary conditions can be fixed by
just including source terms
