Synopsis

template<bool Complex>

gf_lehmann_t<Complex> atomic_g_lehmann (atom_diag<Complex> const & atom,

double beta,

gf_struct_t const & gf_struct,

excluded_states_t excluded_states = {})

The atomic Green’s function, Lehmann representation

Template parameters

• Complex Do we have a diagonalization problem with a complex-valued Hamiltonian?

Parameters

• atom Solved diagonalization problem.
• beta Inverse temperature.
• gf_struct Block structure of the Green’s function, block name -> list of inner indices.
• excluded_states Excluded eigenstates as pairs (subspace index, inner index).

Returns

Atomic Green’s function in the Lehmann representation
