Synopsis

g_wr_t fourier_tr_to_wr (g_tr_cvt g_tr, int nw = -1)

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

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

Parameters

g_tr real-space imaginary time Green’s function \(G_{a\bar{b}}(\tau, \mathbf{r})\)

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