Description of the thesis topic
The PhD student will participate in the SENSES (making Sense of Electrical Noise by Simulating Electrolyte Solutions) research project, coordinated by Benjamin Rotenberg. The general objective is to provide an integrated understanding of electrical fluctuations in bulk, interfacial and confined ionic fluids.
In this context, the PhD student will investigate electric current fluctuations through single nanopores and nanotubes, in order to understand the microscopic origin of the "coloured noise" (generic behaviour with an algebraic frequency dependence at low frequency) observed in experiments. Particle-based simulations will clarify how this behaviour emerges from the combined interactions within the electrolyte and with the solid walls, to interpret the effect of salt concentration, geometry and nature of the confining wall, in collaboration with a leading experimental group.
Candidates should have at the beginning of the contract a Master's degree in Physical Chemistry or in Physics. Some experience in classical molecular or mesoscopic simulation will be appreciated, as well as a good knowledge of the associated theoretical and numerical tools (Statistical Mechanics of liquids...; programming skills e.g. in: Python, Fortran, C, C++, ...). Written/oral communication in English is necessary (knowledge of French is not).
The PHENIX laboratory (Physical chemistry of electrolytes and interfacial nanosystems) is a joint research unit between CNRS and Sorbonne Université. It is located on the Pierre et Marie Curie Campus, in the center of Paris. It consists of ~90-100 people, including academic staff, PhD students and postdoctoral fellows, and conducts research in the fields of Energy (electrochemical storage, recycling...), Health (nanoparticles for imaging, ...) and Environment (waste disposal, water treatment, ...).
The PhD student will be part of the "multiscale modelling and experiments" group and conduct research in the framework of the ERC project SENSES. Access will be provided to computational resources at the lab and University levels.
