Later when removing it, it would still feel the potential due to N electrons since no electron feels a potential due to itself. So the electron energy levels relevant to this process should be calculated fro ...

Notes on noise
... A random walk (RW) is a noise process whose derivative is white noise (WN) — each step in the walk is independent of previous and subsequent steps. Since differentiating f (t) is equivalent to dividing its Fourier transform f˜(ω) by ω, we have fRW (ω) = ω −1 fWN (ω) and K̃RW (ω) = ω −2 K̃WN (ω) ∝ 1/ ...
