Introduction

The aim of this research project is to facilitate the interpretation and understanding of inelastic and quasielastic neutron scattering data by developing a new computer modelling method to model the dynamic structure factor, S(q,omega).

The project is a collaboration between Chalmers University, the European Spallation Source, ISIS Facility and the Niels Bohr Institute. The work will mostly be performed at the ISIS facility, where the position will be based.

In this project S(q,omega) will be calculated using molecular dynamics (MD) simulations while the interatomic potentials will be changed until a quantitative agreement is obtained between the modelled and measured scattering function. The method can be seen as a dynamical correspondence to the Empirical Potential Structure Refinement (EPSR) method used to produce structural models of materials in quantitative agreement with neutron and x-ray diffraction data. It is foreseen that our approach will have similar impact on understanding dynamics as EPSR has on structure. Thus, ESS, ISIS and the user community will benefit enormously from the development of the proposed method.

Further, it will be possible to obtain a considerably deeper understanding of how molecular motions affect the macroscopic properties of a material. Thereby, it will be possible to gain invaluable insight in improving new materials in the areas of chemistry, biology, life science and medicine. Moreover, not only the users of neutron spectroscopy will take advantage of the method, but also the computer simulation community will get a unique possibility to refine model potentials by using this approach.

Description of Institution

ISIS is a world leading facility for condensed matter research using neutron scattering and muon spectroscopy, with a strong scientific user program and extensive international links. ISIS currently operates 30 instruments and, following an additional £21m investment, is currently in the process of building 4 new instruments.

ISIS has a strong record of delivering successful neutron scattering software and this is an opportunity to join an international project with significant scope to lead areas of work.

Job description

You will initially focus on developing a new modelling tool; where the you will be working with experienced software professionals. Soon after the first version of the software package is completed, you will participate in neutron scattering experiments to validate the model against measured data. This step will allow further refinement of the software package. You will also be responsible for documenting the software and writing scientific articles about the developed modelling tool.

You will be part of the team developing and supporting scientific software. Therefore, as part of your work you will interact frequently with the ISIS scientists and will also be supported by the partners at Chalmers University, the European Spallation Source the Niels Bohr Institute. The post will reside within the Scientific Computing section of the ISIS Computing Group.
