Synopsis

g_wr_t fourier_wk_to_wr (g_wk_cvt g_wk)

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

Computes: \(G_{a\bar{b}}(i\omega_n, \mathbf{r}) = \mathcal{F}^{-1} \left\{G_{a\bar{b}}(i\omega_n, \mathbf{k})\right\}\)

Parameters

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

Returns

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