Description
We study flavor current correlators in strongly coupled matter at finite quark and isospin chemical potentials using holography. Finite isospin density qualitatively modifies the low-energy dynamics of charged currents, combining diffusion with flavor precession. We analyze the corresponding quasinormal-mode spectrum and its interplay with the infrared modes associated with the emergent AdS_2 region of the near-extremal geometry. Finally, we discuss how this structure can be incorporated into an extended hydrodynamic description of the current correlators beyond the conventional hydrodynamic regime.
