Statistical Physics

Main subjects: Growing interfaces, phase ordering, coarsening, and percolation.

Other topics of my interest: Absorbing phase transitions, pattern formation, turbulence and active matter.

Toolset

Computational physics: Programming (Fortran, Python, etc.). Monte Carlo simulations. Cluster analysis.
Hard matter: Thin-film growth techniques. Polycrystals. Atomic Force Microscopy.
Soft matter: Liquid crystals. Optical microscopy. Electro-hydrodynamic convection.

Polycrystal

Surface of a CdTe polycrystalline film. The topography was measured using atomic force microscopy. The height fluctuations follow Kardar–Parisi–Zhang scaling laws and distributions. Unpublished result.

Liquid crystal

Twisted nematic liquid crystal after a quench from a turbulent state. Domains are distinguished by right-hand twists (green) or left-hand twists (violet). The largest cluster (orange) is a fractal. Critical Clusters in Liquid Crystals: Fractal Geometry and Conformal Invariance, PRL 134, 178101 (2025).

Clusters in growing interfaces

Sign of the height fluctuations of a simulated KPZ growth model. Positive (negative) signs are painted in violet (green) color. The largest cluster of positive (negative) sign is highlighted in red (blue) color. Universal Coarsening and Giant-Cluster Formation in Growing Interfaces. Submitted to Physical Review Letters.
