Magnetic fluctuations and specific heat in NaxCoO2 near a Lifshitz transition

We analyze the temperature and doping dependence of the specific heat C(T) in Na x CoO 2 . This material was conjectured to undergo a Lifshitz-type topological transition at x=x c =0.62 , in which a new electron Fermi pocket emerges at the Γ point, in addition to the existing hole pocket with large...
