“…These results also explain the results of Lee [12] on the Conserved Lattice Gas (CLG) in 1D, which maps to the A-B annihilation problem. The CLG consists of particles with an exclusion interaction on a 1D lattice, and the dynamics maps to the A-B annihilation problem (with stationary B particles) with the configurations mapping to each other as 0 n+1 → B n and 01 n+1 → φA n , where φ denotes an empty site.…”

“…ρ = 0.5 is also the critical density of the model, and hence the decay exponent for two-species annihilation gives the critical decay exponents for activity for the CLG. Based on the results of this paper, one can say that for initial conditions of the form 1 n+1 0 n+1 , one expects a pure power law with exponent −0.5 for odd n but a logarithmic correction for even n. Lee's measurements [12] on periodic configurations are consistent with this interpretation. Lee also studied the decay for 'natural' initial conditions which can be interpreted to be a mixture of blocks 0011 and 000111.…”

“…Ódor and Menyhárd also argue that this could be an effect of a logarithmic correction to the decay. Lee's results [12] for the 'natural' initial conditions, which show an effective exponent different from and lying between the ones he observed for n even and n odd, can also be explained in this fashion.…”

“…They also argue that the exclusion interaction leads to a marginal (in the field theoretical sense) interaction between the particles, which could lead to a logarithmic correction to the decay. Recent simulations by Lee of the Conserved Lattice Gas (CLG), the dynamics of which also maps to AB annihilation with exclusion, showed an anomalous decay exponent of 0.523 was observed for i.c.s which map to periodic i.c.s of the AB process with even-length blocks [12]. These observed anomalous decay exponents for this important problem have not received an analytical explanation till now.…”

We show that the decay of the density of active particles in the reaction A+B→0 in one dimension, with exclusion interaction, results in logarithmic corrections to the expected power law decay, when the starting initial condition (i.c.) is periodic. It is well known that the late-time density of surviving particles goes as t^{-1/4} with random initial conditions, and as t^{-1/2} with alternating initial conditions (ABABAB⋯). We show that the decay for periodic i.c.'s made of longer blocks (A^{n}B^{n}A^{n}B^{n}⋯) do not show a pure power-law decay when n is even. By means of first-passage Monte Carlo simulations, and a mapping to a q-state coarsening model which can be solved in the independent interval approximation (IIA), we show that the late-time decay of the density of surviving particles goes as t^{-1/2}[ln(t)]^{-1} for n even, but as t^{-1/2} when n is odd. We relate this kinetic symmetry breaking in the Glauber Ising model. We also see a very slow crossover from a t^{-1/2}[ln(t)]^{-1} regime to eventual t^{-1/2} behavior for i.c.'s made of mixtures of odd- and even-length blocks.

Enhancing photogalvanics electrical output in the sphere of solar energy is the goal of the study. The use of fossil fuels is also limitation to energy conversion. The photogalvanic (PG)cell with EDTA + TB + NaLS + CPC + Tween-80 produces superior results than a system with just one surfactant. The photopotential (PP) and photocurrent (PC) of the EDTA+TB + NaLS + CPC + Tween-80 photogalvanics were measured at 689.00 mV and 234.00 uA, respectively. The efficiency and performance of the EDTA+TB+NaLS+CPC+Tween-80 photogalvanics were determined to be 0.2811% and 109.00 minutes, respectively. The photogalvanic system with mixed surfactants (NaLS+CPC+Tween-80) is a productive one with improved electrical characteristics. The performance of PG cells can be slightly improved by using individual surfactants as opposed to surfactant combinations. Surfactant combinations with qualities that are superior to those of the individual components can be used in PG cell applications.
