Phase-field modeling of materials

Supervisor: Dr. Mikko Karttunen

Can extend to MSc?:  Yes

Project Description (Abstract):

I have several projects involving theoretical and computational modeling of materials using the phase-field / phase-field crystal approach. This is a very powerful field-theoretical technique that is based on the Landau theory of phase transitions. In this approach, the material is modelled at a mesoscopic level using a continuous field instead of using atoms. Possible projects include a) modeling eutectics in three dimensions. Eutectics are mixtures of materials which solidify at a temperature that is lower than that of either of the substances. They exhibit very rich physics and are used in a broad range of applications from alloys to corrosion resistant materials, and in materials for 3-D printing. In project b) the phase field approach is used to model multicomponent biological membranes. On top of the curious features of biological (cell) membranes is that they show nanoscale finite-size domains, often called rafts, which have been proposed to be vital for functions of proteins. In this project the membrane is modeled and simulated using a phase-field model.


The student(s) need(s) strong mathematical skills and background in computer simulations or/and programming as the nature of the work is theoretical and computational. The simulations will be done using our in-house developed software called SymPhas.


This project will not be influenced by possible further closures should the pandemic continue.
