Synopsis

g_tr_t fourier_wr_to_tr (g_wr_cvt g_wr, int nt = -1)

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

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

Parameters

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

Returns

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