gw_embedding.iaft.IAFT.w_to_tau_phsym

IAFT.w_to_tau_phsym(Ow, stats)

Fourier transform from Matsubara-frequency axis to imaginary-time axis w/ particle-hole symmetry.

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, …)
