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.

Tunneling Contact

In this paper, we investigate the peculiar features of the tunneling contact between a superlattice and a non-Fermi quantum liquid. The imaginary part of the Green functions are responsible for the non-Fermi liquid density of states. The Green functions have been derived within the framework of the anti-de Sitter/conformal field theory correspondence.
