pole_gf_tau
(tau, poles, weights, beta)¶ Imaginary time Green’s function given by a finite number of poles.
- Parameters

Green’s function is evaluated at imaginary times tau. Only implemented for \(τ ∈ [0, β]\).
- poles, weights(…, N) float array_like or float
Position and weight of the poles.
- betafloat
Inverse temperature
- Returns
- pole_gf_tau(…) float np.ndarray
