This study investigates reaction-diffusion fronts in disordered media, finding the front width exponent deviates from mean-field predictions. At criticality, it matches the 1D exponent, challenging prior research.

Area of Science:

  • Chemical Physics
  • Complex Systems
  • Statistical Mechanics

Background:

  • Reaction-diffusion systems are fundamental to chemical and biological processes.
  • Disordered media introduce complexities, affecting transport and reaction dynamics.
  • Understanding front propagation in such systems is crucial for predicting pattern formation and reaction rates.

Purpose of the Study:

  • To characterize the front dynamics of the A + B --> C reaction-diffusion system in disordered media.
  • To investigate the influence of disorder degree and criticality on front width exponents.
  • To correct erroneous predictions in existing literature regarding 2D percolation clusters.

Main Methods:

  • Simulations of the A + B --> C reaction-diffusion system.

  • Utilizing two-dimensional (2D) percolation models to represent disordered media.
  • Analysis of front width scaling as a function of disorder and proximity to criticality.

    • Main Results:

    • The front width exponent exceeds the mean-field (MF) exponent of 1/6.
    • At criticality, the front width exponent approaches the one-dimensional (1D) value of 1/4.
    • Previous theoretical predictions for 2D percolation clusters at criticality were found to be incorrect.

    Conclusions:

    • Front propagation in disordered media exhibits anomalous scaling behavior.
    • The study highlights the importance of considering dimensionality and disorder in reaction-diffusion processes.
    • Results provide a more accurate understanding of front dynamics in systems with attenuated transport.
