  Recently, there has been great interest in the phenomenon of severe violation
of the Wiedemann-Franz law in graphene Dirac fluids around 75 K, due to the
strong coupling relativistic plasma near the neutral point, where traditional
perturbation theory fails. To explain this phenomenon, this article proposes a
holographic dual two-current axion coupling model, describing the interaction
between electrons and holes in graphene near the charge neutrality point (CNP)
and revealing the related physical mechanism. The study shows that the
holographic two-current model aligns with experimental results at $100\mu
m^{-2}$,and correctly predicts conductivity as temperature increases.
Additionally, the article explores the behavior of $\beta+\gamma$ and its
impact on conductivity and thermal conductivity. The results suggest a
frictional effect between electrons and holes. Consequently, this study
provides us with a clearer understanding of the properties of graphene Dirac
fluids and further confirms the reliability of the holographic duality method.
