dc.descriptionIt is shown that the charge susceptibility in nearly half-filled two-dimensional (2D) metals, with technically nested Fermi surface, shows anomaly at the wavevector different from that for the spin susceptibility at low temperatures. Namely charge degrees of freedom behave there as if their ``Fermi surface" corresponded to that of ``holes" created in the Mott insulator. Such anomaly is caused by the Aslamazov-Larkin type contribution of 2D antiferromagnetic spin fluctuations. This phenomenon gives a possible clue to resolve the paradox of normal state properties of high-$T_{\rm c}$ cuprates {\it starting}\/ from the Fermi-liquid fixed point.
