fourier_tr_to_wr

Synopsis:

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

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

Parameters

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

Return value

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

Documentation

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