triqs.gf.descriptors.SemiCircular(half_bandwidth, chem_potential=0.0)[source] Hilbert transform of a semicircular density of states, i.e.
\[g(z) = \int \frac{A(\omega)}{z-\omega} d\omega\]where \(A(\omega) = \theta( D - |\omega|) 2 \sqrt{ D^2 - \omega^2}/(\pi D^2)\).
(Only works in combination with frequency Green’s functions.)
