In the last decade, motivated by the concept of Planckian relaxation and thepossible existence of a quantum critical point in cuprate materials,holographic techniques have been extensively used to tackle the problem ofstrange metals and high-$T_c$ superconductors. Among the various setups, thelinear axion Gubser-Rocha model has often been considered as a promisingholographic model for strange metals since endowed with the famous linear in$T$ resistivity property. As fiercely advocated by Phil Anderson, beyond$T$-linear resistivity, there are several additional anomalies unique to thestrange metal phase, as for example a Fermi liquid like Hall angle -- thefamous problem of the two relaxation scales. In this short note, we show thatthe linear axion holographic Gubser-Rocha model, which presents a singlemomentum relaxation time, fails in this respect and therefore is not able tocapture the transport phenomenology of strange metals. We prove our statementby means of a direct numerical computation, a previously demonstrated scalinganalysis and also a hydrodynamic argument. Finally, we conclude with anoptimistic discussion on the possible improvements and generalizations whichcould lead to a holographic model for strange metals in all their glory.
