On the Cross-Correlation of a Ternary

In this paper, we investigate into the crosscorrelation of a ternary m-sequence m(t) of period 3 − 1 and its decimated sequence m(dt) by d = (3 +1) 8 , where n = 2m = 4k + 2. It is shown that the magnitude of the crosscorrelation values is upper bounded by 2 √ 3n + 1.

Thermodynamic time asymmetry in nonequilibrium fluctuations

We here present the complete analysis of experiments on driven Brownian motion and electric noise in a RC circuit, showing that thermodynamic entropy production can be related to the breaking of time-reversal symmetry in the statistical description of these nonequilibrium systems. The symmetry breaking can be expressed in terms of dynamical entropies per unit time, one for the forward process a...

Time-symmetric fluctuations in nonequilibrium systems.

For nonequilibrium steady states, we identify observables whose fluctuations satisfy a general symmetry and for which a new reciprocity relation can be shown. Unlike the situation in recently discussed fluctuation theorems, these observables are time-reversal symmetric. That is essential for exploiting the fluctuation symmetry beyond linear response theory. In addition to time reversal, a cruci...

Capillary-to-Bulk Crossover of Nonequilibrium Fluctuations in the Free Diffusion of a Near-Critical Binary Liquid Mixture.

We have studied the nonequilibrium fluctuations that occur at the interface between two miscible phases of a near-critical binary mixture during a free-diffusion process. The small-angle static scattered intensity is the superposition of nonequilibrium contributions that are due to capillary waves and to bulk fluctuations. A linearized hydrodynamic description of the fluctuations allows us to i...
