Synopsis:

triqs_tprf::g_wr_t fourier_wk_to_wr (triqs_tprf::g_wk_cvt g_wk)

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

Parameters

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

Return value

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

Documentation

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