Fluctuation ratios in the absence of microscopic time reversibility.
نویسندگان
چکیده
We study fluctuations in diffusion-limited reaction systems driven out of their stationary state. Using a numerically exact method, we investigate fluctuation ratios in various systems which differ by their level of violation of microscopic time reversibility. Studying a quantity that for an equilibrium system is related to the work done to the system, we observe that under certain conditions oscillations appear on top of an exponential behavior of transient fluctuation ratios. We argue that these oscillations encode properties of the probability currents in state space.

Quantifying reversibility in a phase-separating lattice gas: an analogy with self-assembly.
We present dynamic measurements of a lattice gas during phase separation, which we use as an analogy for self-assembly of equilibrium ordered structures. We use two approaches to quantify the degree of reversibility of this process: First, we count events in which bonds are made and broken; second, we use correlation-response measurements and fluctuation-dissipation ratios to probe reversibilit...
متن کاملEffect of Twisted Tape Baffles on Pressure Drop, Fluctuation and Expansion Ratios in gas - Solid Fluidized Bed
In the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. Experimental investigation has been carried out in cylindrical column with and without twisted tapes. Twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different...
متن کاملFluctuation formula for nonreversible dynamics in the thermostated Lorentz gas.
We investigate numerically the validity of the Gallavotti-Cohen fluctuation formula in the two- and three-dimensional periodic Lorentz gas subjected to constant electric and magnetic fields and thermostated by the Gaussian isokinetic thermostat. The magnetic field breaks the time reversal symmetry, and by choosing its orientation with respect to the lattice, one can have either a generalized re...
متن کاملContinuous time random walks in closed and open single-molecule systems with microscopic reversibility
– Continuous time random walk (CTRW) is studied with a new dynamic equation based on the age-structure of states. For a CTRW in a closed molecular system, two necessary conditions for microscopic reversibility are introduced: 1) independence of transition direction and waiting time for every state and 2) detailed balance among the transition probabilities. Together they are also sufficient cond...
متن کاملDetailed fluctuation theorem for mesoscopic modeling.
The detailed fluctuation theorem is derived. The basic assumptions are phase space incompressibility (Liouville's theorem) and time reversibility on the microscopic level. The theorem relates the conditional probability to end up in a mesoscopic state Gamma(B) at time t(B) , starting from Gamma(A) at time t(A) , to the time-reversed process. The ratio of these two probability densities is relat...
