**Description du sujet**:
This thesis focuses on:
Hydrodynamic modeling: Developing numerical methods to solve stochastic 3D Navier-Stokes equations, incorporating laser energy deposition with high-performance GPU computing in Julia.

Machine learning for multi-scale simulations: Designing neural networks combining experimental data and physical constraints to model nanoscale fluid dynamics.

Self-organization dynamics: Investigating convective instabilities leading to periodic nanostructures.

Chiral structure control: Integrating optical torque effects (spin and orbital angular momentum) to predict and generate asymmetric nanostructures.

This research aims to push the boundaries of current laser nanostructuring technologies through innovative numerical and AI-driven approaches.
