Synopsis

1. std::tuple<chi_tr_t, chi_r_t> dynamic_and_constant_to_tr (chi_wk_vt Gamma_pp_dyn_wk,

   chi_k_vt Gamma_pp_const_k)
2. std::tuple<chi_Dtr_t, chi_r_t> dynamic_and_constant_to_tr (chi_Dwk_vt Gamma_pp_dyn_wk,

   chi_k_vt Gamma_pp_const_k)

Documentation

1) Fourier transform Gamma parts to imaginary time and real-space

2) Fourier transform Gamma parts to imaginary time and real-space

Parameters

• Gamma_pp_dyn_wk : The dynamic part of Gamma, which converges to zero for \(\omega_n \rightarrow \infty\).

• Gamma_pp_const_k : The part of Gamma that is constant in Matsubara frequency space \(\Gamma(\mathbf{k})\).

Returns

Tuple of Gamma_pp_dyn_tr, the dynamic part of Gamma, which converges to zero for \(\omega_n \rightarrow \infty\), but now in \(\tau\)-space, Gamma_pp_const_r, the constant part of Gamma in real-space.
