Synopsis:

triqs_tprf::g_wk_t fourier_wr_to_wk (triqs_tprf::g_wr_cvt g_wr)

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

Parameters

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

Return value

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

Documentation

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