Inferring entropy production in anharmonic Brownian gyrators

Enhanced directionality of active processes in a viscoelastic bath

“…The entropy production rate of this system can be calculated using the Fokker-plank based method as described in [14,16,63,104]. Starting from an arbitrary initial condition for x, X and x 0 , the system will reach to a nonequilibrium steady state in the long time with a characteristics probability distribution (P ss (Y)) and current (J ss (Y)) that can be described in terms of the steady state covariance matrix σ as shown in equation (A.9).…”

“…The thermodynamics of such processes has been extensively studied in recent decades, particularly in the context of stochastic thermodynamics [5,6]. This field has focused on various aspects, including fluctuation relations [7][8][9], as well as advancements in stochastic inference techniques [10][11][12][13][14][15][16][17][18]. These theories have now been well tested in experiments, and have provided us with accurate estimates of thermodynamic quantities, such as equilibrium free energy differences and dissipation for specific biophysical systems [19,20] and efficiencies of molecular motors [21,22].…”
