摘要:
Some important consequences of the time-reversal symmetry of a stationary random process are highlighted. We discuss a connection between fluctuation-dissipation theorems and model macroscopic Langevin equations. Based on the property of statistical time reversibility we obtain the exact result for steady-state distribution of classical harmonic oscillator with fluctuating frequency. (C) 2010 Elsevier B.V.
