Thermodynamic and Kinetic Bounds for Finite-frequency Fluctuation-Response (opens in new tab)

arXiv:2602.18631v1 Announce Type: new Abstract: Fluctuation-response relations encode fundamental constraints on nonequilibrium systems. While time-domain static response is bounded by activity and entropy production, finite-frequency extensions for time-dependent perturbations remain largely unexplored. Here, we derive frequency-domain fluctuation-response inequalities for steady-state Markov processes with time-dependent perturbations. For barrier and entropic perturbations, the spectral s...
