Active Jarzynski and Crooks Relations for Driven Jump-Diffusions
Abstract
Non-conservative active driving breaks detailed balance in non-Gaussian jump-diffusions, obscuring the connection between external protocol work, housekeeping dissipation, and free-energy differences. Here, we establish exact finite-time fluctuation relations for driven Markov jump-diffusions---encompassing infinite-activity Lévy processes---by comparing path probabilities under the forward and current-reversed dual dynamics relative to the instantaneous steady state (ISS). We derive a trajectory-level decomposition of total entropy production that cleanly separates transient state relaxation, housekeeping heat, and external protocol driving. When the ISS takes a Gibbsian form, gauge-tilting the dual path measure yields an Active Jarzynski equality, ⟨exp[−(W+Δsact)]⟩π0=e−ΔF, which incorporates active housekeeping entropy Δsact alongside mechanical work W and coexists with the conventional Jarzynski equality. Under protocol reversal, this dual framework further reveals an Active Crooks relation, where the asymmetry between forward and reverse work distributions is governed by the conditional exponential average of active dissipation. Our results provide a framework for recovering free-energy differences in driven jump-diffusions with Gibbsian instantaneous steady states and for characterizing active irreversibility through trajectory statistics.
