Background:

Characterizing natural structures in complex physical systems is challenging.
Existing methods may not fully capture multi-scale organizational principles.
Understanding emergent structures is crucial for predicting material properties.

Purpose of the Study:

To present a general method for identifying natural structures in complex physical systems.
To apply multi-scale network analysis and community detection for structural characterization.
To explore the relationship between identified structures and physical transitions.

Main Methods:

Developed a method based on multi-scale network analysis and community detection.
Constructed network representations ('replicas') from interatomic potentials or correlations.
Applied multiresolution community detection using information-based correlations among replicas.

Main Results:

Successfully identified dominant, disjoint, or overlapping structures and length scales.
Applied the method to simulated binary and ternary systems and experimental ZrPt data.
Observed potential links between structural changes and physical transitions or phase transitions.

Conclusions:

The developed network analysis method effectively characterizes natural structures in complex physical systems.
The findings suggest a correlation between identified community structures and physical phenomena.
The method provides insights into material rigidity and shear penetration depth in amorphous systems.
