Front propagation in A $\to$ 2A, A $\to$ 3A process in 1d: velocity, diffusion and velocity correlations

Niraj Kumar, Goutam Tripathy

We study front propagation in the reaction diffusion process ${A \to ε 2 A, A \to ε_{t} 3 A}$ on a one dimensional (1d) lattice with hard core interaction between the…

Velocity of front propagation in the epidemic model $A + B \to 2 A$

Niraj Kumar, Goutam Tripathy

We study front propagation in the irreversible epidemic model $A + B \to 2 A$ in one dimension. Here, we allow the particles $A$ and $B$ to diffuse with rates $D_{A}$ and $D_{B}$ , which, i…

Velocity and diffusion coefficient of $A + A \leftrightarrow A$ reaction fronts in one dimension

Niraj Kumar, Goutam Tripathy

We study front propagation in the reversible reaction-diffusion system A + A <-> A on a 1-d lattice. Extending the idea of leading particle in studying the motion of the front we w…

Roughness of Sandpile Surfaces

J. G. Oliveira, J. F. F. Mendes, G. Tripathy

We study the surface roughness of prototype models displaying self-organized criticality (SOC) and their noncritical variants in one dimension. For SOC systems, we find that two se…
