Missions

Machine-learning interaction potentials (MLIP) have been recently proposed to bridge
the gap between quantum accurate calculations and fast empirical modeling. In this project, we will use a machine-learning method that we are currently developing and that is named Physical LassoLars Interaction Potential (PLIP). In particular, the retained candidate will work on two fundamental improvements for PLIP. He/she will implement an on-the-fly training of the potential which will unlock transferability issues that are often observed in machine-learning potential. Then, he/she will tackle the challenges related to long-range interactions by explicitly incorporating electrostatic effects with machine-learned Coulombic charges.

Activities

- Hands-on PLIP method
- Implement on-the-fly training
- Include electrostatic charges
- Test method on different materials

Skills

- CPP coding
- Molecular dynamics LAMMPS
- Force field construction
- Machine-learning

Work Context

The work will be carried out in the group SINanO of CEMES located in Toulouse. The hired candidate will be supervised by Julien Lam in collaboration with Magali Benoit and Rémi Arras.
