Fluctuations of jamming coverage upon random sequential adsorption on homogeneous and heterogeneous media.
The fluctuations of the jamming coverage upon random sequential adsorption (RSA) are studied using both analytical and numerical techniques. Our main result shows that these fluctuations (characterized by sigma(thetaJ)) decay with the lattice size according to the power law sigma(thetaJ) proportional, variant L(-1/nu). The exponent nu depends on the dimensionality D of the substrate and the fra...
متن کاملScaling behavior near jamming in random sequential adsorption.
For the random sequential adsorption model, we introduce the "availability" as a variable corresponding to the number of available locations in which an adsorbate can be accommodated. We investigate the relation of the availability to the coverage of the adsorbent surface over time. Power law scaling between the two is obtained both through numerical simulations and analytical techniques for bo...
متن کاملScaling behavior of jamming fluctuations upon random sequential adsorption
It is shown that the fluctuations of the jamming coverage upon Random Sequential Adsorption (σθJ ), decay with the lattice size according to the power-law σθJ ∝ L−1/νJ , with νJ = 2 2D−df , where D is the dimension of the substrate and df is the fractal dimension of the set of sites belonging to the substrate where the RSA process actually takes place. This result is in excellent agreement with...
متن کاملFluctuations of the partial filling factors in competitive random sequential adsorption from binary mixtures.
Competitive random sequential adsorption on a line from a binary mix of incident particles is studied using both an analytic recursive approach and Monte Carlo simulations. We find a strong correlation between the small and the large particle distributions so that while both partial contributions to the fill factor fluctuate widely, the variance of the total fill factor remains relatively small...
متن کاملShapes for maximal coverage for two-dimensional random sequential adsorption.
The random sequential adsorption of various particle shapes is studied in order to determine the influence of particle anisotropy on the saturated random packing. For all tested particles there is an optimal level of anisotropy which maximizes the saturated packing fraction. It is found that a concave shape derived from a dimer of disks gives a packing fraction of 0.5833, which is comparable to...
