gw_embedding.iaft.IAFT.w_to_tau

IAFT.w_to_tau(Ow, stats)[source]

Fourier transform from Matsubara-frequency axis to imaginary-time axis.

Parameters:

Ow – numpy.ndarray Matsubara-frequency object with dimensions (nw, …)
stats – str statistics, ‘f’ for fermions and ‘b’ for bosons

Returns:

numpy.ndarray Imaginary-time object with dimensions (nt, …)
