Synopsis

g_wk_t fourier_wr_to_wk (g_wr_cvt g_wr)

Fast fourier transform of imaginary frequency Green’s function from real-space to k-space

Computes: \(G_{a\bar{b}}(i\omega_n, \mathbf{k}) = \mathcal{F} \left\{ G_{a\bar{b}}(i\omega_n, \mathbf{r}) \right\}\)

Parameters

  • g_wr real-space imaginary frequency Green’s function \(G_{a\bar{b}}(i\omega_n, \mathbf{r})\)

Returns

k-space imaginary frequency Green’s function \(G_{a\bar{b}}(i\omega_n, \mathbf{k})\)
