Abstract

We investigate the properties of holographic fermions in charged Lifshitz black holes at finite temperature through the AdS/CFT correspondence. In the charged Lifshitz background with the dynamical exponent z=2z=2, we find that the dispersion relation is linear. The scaling behavior of the imaginal part of the Green function relative to k=kkFk_{\perp}=k-k_F is also discussed. We find, although the system has linear dispersion relation and quadratic quasi-particle width, it does not satisfy Luttinger's theorem. We also find that the variation of the scaling parameters α\alpha and β\beta is small as the charge qq varies. Furthermore, we also discuss the effect of the dynamical exponent zz by considering the cases z=4z=4 and z=6z=6 and show that ImGiiImG_{ii} become smooth when the dynamical exponent zz increases.
