A fully-funded PhD position is available in the Laboratoire de Physique et Chimie Théoriques at the University of Lorraine (Metz, France).

KEYWORDS:
Quantum dynamics, Stochastic simulations, Self-assembled p-stacking, Exciton transfer, Energy dissipation, Time-resolved spectroscopy

SUBJECT DETAILS:
The goal of the project it to develop theoretical models and numerical tools to allow studying long-range energy transfer in self-assembled biological systems. In particular, we will focus on phenanthrene/pyrene p-stacks embedded in a DNA scaffold, motivated by recent time-resolved spectroscopic experiments that revealed the relative importance of coherent energy transport. We follow a hierarchical approach to provide a balanced description of these inherently multi scale systems. First, the systems will be parametrized atomistically using state-of-the-art quantum chemistry methods. Second, the excitonic transfer dynamics will be investigated using stochastic dissipative dynamical methods tailored specifically for such systems. Dephasing and energy relaxation effects due to the contact with the DNA environment occur on the same timescale as photon absorption, and they are bound to influence the energy transfer efficiency. Atomistic understanding of the dissipative exciton transport mechanism will allow to improve the design of similar artificial light-harvesting antennae.

CANDIDATE PROFILE:
Master degree in Physics or equivalent education.
Good knowledge of quantum mechanics.
Good programming skills (Python, Fortran, and/or C++).
Knowledge of quantum chemistry programs (e.g. Gaussian).
At least level B2 in English and preferably some French knowledge.
