Area of Science:

  • Statistical Mechanics
  • Network Science
  • Complex Systems

Background:

  • Small world networks exhibit unique topological properties.

  • To analyze the behavior of order parameters and statistical properties of these networks.

Main Methods:

  • Utilized replicated transfer matrices within the replica symmetric approximation.
  • Employed population dynamics techniques to examine equilibrium states.
  • Performed Glauber simulations for validation.

Main Results:

  • The degree distribution of the small world networks was found to adopt a Poisson-like form.
  • This Poisson-like distribution was observed both within and outside the ordered phase.
  • Order parameters at total equilibrium were successfully examined.

Conclusions:
