  "abstract": "A thermodynamic system is driven into a nonequilibrium condition when a time-dependent force or a nonconservative force represented by a protocol $\\lambda(t)$ is applied. Such a system is time irreversible in the sense that the motion under a protocol $\\lambda(0\\leq t\\leq \\tau)$ and the time-reversed motion under $\\lambda(\\tau-t)$ are not equally probable. We investigate a stochastic echo phenomenon in which a system is controlled by an optimal protocol to display the time-reversed motion. The optimal protocol is derived for a Langevin system. For the time-dependent driving case, simple harmonic oscillator systems are found to display the perfect stochastic echo phenomenon. We also show that any system driven by a time-independent nonconservative force has a dual system displaying the perfect stochastic echo phenomenon. Our study provides a novel perspective on the time-irreversibility of nonequilibrium systems.",
