We discuss the zeroes and poles of the determinant of the retarded Greenfunction ($\det G_R$) at zero frequency in a holographic system of chargedmassless fermions interacting via a dipole coupling. For large negative valuesof the dipole coupling constant $p$, $\det G_R$ possesses only poles pointingto a Fermi liquid phase. We show that a duality exists relating systems ofopposite $p$. This maps poles of $\det G_R$ at large negative $p$ to zeroes of$\det G_R$ at large positive $p$, indicating that the latter corresponds to aMott insulator phase. This duality suggests that the properties of a Mottinsulator can be studied by mapping the system to a Fermi liquid. Finally, forsmall values of $p$, $\det G_R$ contains both poles and zeroes (pseudo-gapphase).
