| 13 | $\vec{A}_{\vec{k}}$ is a random complex vector subject to |
| 14 | |
| 15 | $|\vec{A}_{\vec{k}}| \propto k^{\beta}$ for $k < k_{\max}$ |
| 16 | |
| 17 | and |
| 18 | |
| 19 | $\vec{A}_{\vec{k}} \cdot \vec{k} = 0$ |
| 20 | |
| 21 | We also want $\vec{a}$ to be real, so |
| 22 | |
| 23 | $\vec{A}_{\vec{-k}} = \vec{A}_{\vec{k}}$ |
| 24 | |
| 25 | However, in the code - it looks like both are chosen randomly, and then the real part of the transform is taken. I have to think about the implications of this... |
