Mattias Marklund - Modelling of Physical Transport Processes and Charge Dynamics in Photosynthesis

Home

Our research focuses on the modelling of physical systems, in particular charge transport, collective, and nonlinear effects. Such models have a wide range of applicability, and the knowledge obtained from one physical system can often be applied to a completely different system, due to similarities in the mathematical structures of the models. Thus, the strength of our research lies in generality, and in this respect we may learn things from, e.g. ocean waves, that are applicable to optical fibres or to the quantum transport of charges in nanoscale devices.

We have paid particular attention to problems concerning so-called plasma systems, i.e. electrically conducting gases, in which the collective nature of the plasma constituents gives rise to long-range phenomena, instead of close-range collisional interactions. Instead of being just a game of billiards, the charges move and create electric and magnetic fields that further interact with particles at large distances. Such interactions are extremely important in many applications, ranging from semiconductors to welding flames. As many fundamental properties rely on charge transport, understanding the dynamics of such plasmas can be an important tool for treating a diverse set of systems.
Many important processes in biological systems are governed by charge transport phenomena, photosynthesis being no exception. In particular, we have chosen to study the problem of proton transport in PSII, of fundamental importance for the understanding of photosynthesis. Here we are developing new self-consistent models for proton transfer and we are further implementing these codes in numerical schemes in order to make comparisons with experiments.
