Synopsis
template<bool Complex>block_gf<imfreq> atomic_g_iw (gf_lehmann_t<Complex> const & lehmann,gf_struct_t const & gf_struct,mesh::imfreq const & mesh) template<bool Complex>double beta,gf_struct_t const & gf_struct,int n_iw,excluded_states_t const & excluded_states = {})
Documentation
1) The atomic Matsubara Green’s function, constructed from precomputed Lehmann representation
2) The atomic Matsubara Green’s function, possibly with excluded states (none by default)
Template parameters
Complex Are we using Lehmann representation with complex matrix elements?
Parameters
lehmann Lehmann representation.
gf_struct Block structure of the Green’s function, block name -> list of inner indices.
mesh Matsubara mesh used in construction.
atom Solved diagonalization problem.
beta Inverse temperature.
n_iw Number of Matsubara frequencies.
excluded_states Excluded eigenstates as pairs (subspace index, inner index).
Returns
Atomic Green’s function \(G_{at}(i\omega)\).
