Synopsis

triqs::gfs::gf<triqs::mesh::refreq> evaluate (triqs::mesh::refreq const & grid, double eta)

Evaluate diagonal part of the real-frequency Green’s function on a chosen grid based on the precomputed Nevanlinna factorization

Parameters

  • grid - real frequency grid

  • eta - Lorentzian broadening

Returns

Real-frequency matrix-valued TRIQS Green’s function on a chosen grid.
