Here the solution, a function to create a randomized time-series starting from a PSD:
def gen_pkfield(nsample=100, alpha=-11.0 / 3, fknee=1, fsample=2.5): # sampling per block
ufreq = np.fft.fftfreq(n=nsample+1, d=1./fsample)[1:] # the Discrete Fourier Transform sample frequencies (with negative values), [1:] to solve the DC
kfreq = np.sqrt(...
