Fermi Liquid Behavior

We study the fermionic spectrum with Weyl correction, which exhibits the non-Fermi liquid behavior. Also, we find that both the height of the peak of the fermionic spectrum and the dispersion relation exhibit a nonlinearity with the variety of the Weyl coupling parameter [Formula: see text], which means that such nonlinearity may be ascribed to one of the Maxwell field. Another important property of this system is that for [Formula: see text], the degree of the deviation from Fermi liquid is heavier than that for [Formula: see text]. It indicates that there is a transition of coupling strength in the dual boundary field theory.
