An exact identity decomposes the power spectrum of general observables into a quadratic form of local responses at the same frequency for nonequilibrium steady states.
Local perturbations in nonequilibrium Langevin dynamics induce linear relations between stationary densities and currents at different positions due to an underlying one-dimensional response structure.
