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 \(G_{at}(i\omega)\).
