The covariance of a stationary process X is diagonalized by Fourier transform. It does not take into account the complex phase and defines Gaussian maximum entropy models. We introduce general family harmonic moments, which rely on phases to capture non-Gaussian properties. They are defined as Hˆ(LX), where L linear operator Hˆ non-linear multiplies each coefficient integers. can also be calcul...

A bstract We investigate cosmological phase transitions in various composite Higgs models consisting of four-dimensional asymptotically-free gauge field theories. Each model may lead to a confinement-deconfinement transition and associated with the spontaneous breaking global symmetry that realizes Standard Model as pseudo-Nambu-Goldstone boson. Based on argument universality, we discuss order ...
