Missions

The postdoctoral researcher will be part of the “Irregularité” team in LPMC et will be working with Thomas Philippe on modeling crystallization in ionic solution (ANR TITANS project). This work will be done in close collaboration with experiments performed by a team in Toulouse (Polytech') and one in CEA Saclay. A Good knowledge in nucleation theory, as well as a solid experience in numerical simulation is required, ideally in cluster dynamics.

Activités

The objective of the project is to understand the role of transients in the crystallization processes in ionic solution. It has been highlighted that in a large number of systems (such as CaCO3), crystal formation is non-classical and may require the formation of amorphous precursors and/or involve a liquid-liquid phase transition (LLPS) preceding the formation of the crystal. The postdoctoral researcher will be in charge of formulating theoretical and/or numerical tools based on the most recent developments in nucleation theories (mesoscopic and multivariable theories) in order to understand the role of precursors. The theoretical developments and simulation results will be compared to experimental data from our partners at CEA Saclay and Toulouse.

Compétences

The candidate must hold a PhD in physics in the field of condensed matter or statistical physics, preferably with a good knowledge of phase transitions, as evidenced by at least one publication. The candidate should be able to work in a team on multidisciplinary projects as the project lies at the interface of physics and chemistry, and should have also demonstrated, as far as possible, their autonomy as a researcher. Experience in numerical simulations is required, such as Monte Carlo, cluster dynamics, phase field, or molecular dynamics. Proficiency in English (both spoken and written) and good skills in analytical calculation is mandatory.

Contexte de travail

The PMC (Laboratory of Condensed Matter Physics) is one of the 22 research laboratories at the research center of the École Polytechnique, working at the forefront of interdisciplinary scientific, technological, and societal challenges. As part of the Directorate of Education and Research of the École Polytechnique, the Laboratory of Condensed Matter Physics is a joint research unit (École Polytechnique/CNRS) whose work is organized around two fundamental axes: nanoscience and the physics of irregularity. The branch of physics that seeks to understand the solid, liquid, or intermediate states of matter (such as gels, pastes, foams, etc.) in terms of their structure, properties, and collective phenomena related to the interactions between their constituent particles, condensed matter physics is a science that lays the groundwork for countless technological advancements.

Contraintes et risques

In the context of the ANR project, short travel periods within France (CEA SAclay, Polytech'Toulouse) should be expected.
