gftool.pole_gf_tau
- gftool.pole_gf_tau(tau, poles, weights, beta)
Imaginary time Green’s function given by a finite number of poles.
- Parameters:
- tau(…) float array_like
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:
- (…) float np.ndarray
Imaginary time Green’s function.
