Statistical physics of long dynamical trajectories for a system in contact with several thermal reservoirs

Abstract: For a system in contact with several reservoirs r at different inverse-temperatures βr, we describe how the Markov jump dynamics with the generalized detailed balance condition can be analyzed via a statistical physics approach of dynamical trajectories [C(t)] 0≤t≤T over a long time interval T → +∞. The relevant intensive variables are the time-empirical density ρ(C), that measures the fractions of time spent in the various configurations C, and the time-empirical jump densities kr(C , C), that measure the fre… Show more

“…measure the density of jumps from one configuration y to another configuration x. The joint probability to see the empirical density ρ(x) and the empirical flows q(x, y) follows the large deviation form for large T [25,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]]…”

“…Indeed, the initial classification of large deviations into three nested levels (see the reviews [22][23][24] and references therein), with Level 1 for empirical observables, Level 2 for the empirical density, and Level 3 for the empirical process, has been more recently supplemented by the Level 2.5 concerning the joint distribution of the empirical density and of the empirical flows. The rate functions at Level 2.5 are explicit for various types of Markov processes, including discrete-time Markov chains [24][25][26][27][28][29], continuous-time Markov jump processes [25,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] and Diffusion processes [28,29,33,34,37,[47][48][49]. As a consequence, the explicit Level 2.5 can be considered as a starting point from which many other large deviations properties can be derived via contraction.…”

“…(ii)The second contribution involving the jump rate λ(y) and the jump probability Π(x|y) corresponds to the usual rate function for Markov jump processes [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]…”

“…On one hand, the fluctuations of the empirical time-averaged density, of the empirical time-averaged current and of the empirical time-averaged jump-flow of a long dynamical trajectory can be analyzed using the explicit large deviations at Level 2.5 for both continuous-time Markov Jump processes [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] and for Diffusion processes [18,19,22,[30][31][32][33][34]. This Level 2.5 can be then contracted to obtain the large deviations properties of any time-additive observable of the dynamical trajectory.…”

“…While the initial classification involved only three nested levels (see the reviews [17][18][19] and references therein), with Level 1 for empirical observables, Level 2 for the empirical density, and Level 3 for the empirical process, the introduction of the Level 2.5 has been a major progress in order to characterize the joint distribution of the empirical density and of the empirical flows. Its essential advantage is that the rate functions at Level 2.5 can be written explicitly for general Markov processes, including discrete-time Markov chains [19][20][21][22][23][24], continuous-time Markov jump processes [20,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] and Diffusion processes [23,24,28,29,32,[42][43][44][45]. As a consequence, the explicit Level 2.5 can be considered as the central starting point from which many other large deviations properties can be derived via the appropriate contraction.…”
