One-dimensional Lennard-Jones chains exhibit complex behaviors like synchronization or breaking, influenced by noise and friction. These dynamics, including synchronization time and Lyapunov exponents, are sensitive to particle count and the noise-to-friction ratio.

Area of Science:

  • Physics
  • Statistical Mechanics
  • Computational Physics

Background:

  • Lennard-Jones chains are fundamental models in condensed matter physics.
  • Understanding the dynamics of such systems is crucial for various applications.

Purpose of the Study:

  • To investigate the equilibrium Langevin dynamics of one-dimensional Lennard-Jones chains.
  • To determine the influence of noise strength, friction, and particle number on chain behavior.

Main Methods:

  • Simulations of one-dimensional Lennard-Jones chains under equilibrium Langevin dynamics.
  • Analysis of synchronization, breaking, and desynchronization phenomena.

Main Results:

  • Chain behavior (synchronization, breaking, desynchronization) is dependent on noise strength, friction, and particle number.

  • Synchronization time and maximal Lyapunov exponent are functions of particle number and the noise-to-friction ratio.

    • Conclusions:

    • The study reveals rich dynamical behaviors in simple one-dimensional chains.
    • Parameter tuning allows control over chain synchronization and stability.
