AB In this paper, we study the fate of the holographic zero sound mode at finitetemperature and non-zero baryon density in the deconfined phase of the Sakai-Sugimotomodel of holographic QCD. We establish the existence of such a mode for a wide rangeof temperatures and investigate the dispersion relation, quasi-normal modes, and spectralfunctions of the collective excitations in four different regimes, namely, the collisionlessquantum, collisionless thermal, and two distinct hydrodynamic regimes. For sufficientlyhigh temperatures, the zero sound completely disappears, and the low energy physics isdominated by an emergent diffusive mode. We compare our findings to Landau-Fermiliquid theory and to other holographic models
