Transformation of clusters in a matrix & Description of composite systems

Percolation transitions, geometric transformation of related structures, anisotropy of properties

Percolation process animation showing cluster formation

🔍

What?

We model and explain threshold phenomena - why systems and materials have new macroscopic properties.

⚡

Way?

Classical percolation theories describe infinite systems. We study transformations in real systems with given sizes and complex geometries of objects.

🔄

How?

We have developed specialized software that can calculate any parameters of the new structure.

🌍

Where?

Our methods are applicable to physical, economic, social, chemical, and biological systems and will help you understand and explain your experimental results.
