template<typename T >
void cntr::get_ret ( const int  i,
const int  j,
std::complex< T > &  G_ret,
herm_matrix_timestep_view< T > &  G 
)
inline

Returns the retarded component of a hermitian contour function at given times.

Purpose

Returns the retarded component \( G^\mathrm{R}(t_i,t_j) \) at given times \( t_i\) and \( t_j\). We assume \(G^\mathrm{R}(t_i,t_j)\) can be analytically continued to \( j > i\), for which the hermitian conjugate \(G^\ddagger\) is used.

Parameters
i

[int] Index of time \( t_i\) .

j

[int] Index of time \( t_j\) .

G_ret

[complex<T>] The retarded component (scalar GF).

G

[herm_matrix_timestep_view] Contour function G
