A post-doctoral researcher position is available at the Department of Physics in the Faculty of Natural Sciences and Technology. The appointment has a duration of 3 years with the possibility of until 1year extension with 25% teaching duties in agreement with the department. The position is financed by the NTNU digitalization program and has a special responsibility of carrying out atomistic DFT and Monte Carlo simulations for the project ALLDESIGN as well as developing the associated computational platform.

Information of the ALLDESIGN project

The primary objective is to create a digital materials design platform for intermetallic alloy design. The project focuses on aluminium-based alloys, which are of great importance for the Norwegian industry. ALLDESIGN will investigate the physical processes behind slow-diffusion precipitation phenomena starting from atomistic scale and in silico. Our goal is to develop efficient theoretical methods to understand materials properties at different length and time scales and to limit costly trial-and-error measurements in the laboratory. Such output can considerably help in materials screening and finding optimal thermochemical treatment conditions. Complementary to the theoretical work will be experimental high-resolution characterization (including development of data processing algorithms) and validation of the theoretical results. Finally, the data from the multiscale modelling approach will be used for digitalization of the alloy manufacturing process in the newly invested 3D stretch-bending machine. The project involves a simultaneous recruitment of 1 post-doctoral fellow and 4 PhD students in complementary research areas within the same NTNU digital transformation call.

Job description

We seek applicants with the expertise and motivation to develop computational modeling of intermetallic alloys based on the cluster expansion (CE) formalism for atomistic simulations. To optimize the synergetic efforts in ALLDESIGN, we are seeking a candidate (PD1) with the primary competence within atomistic modelling of materials (DFT, Monte Carlo) and good programming skills. The candidate should contribute actively to the ALLDESIGN project by taking care of the simulation activities and software development at the atomistic level and linking these methods with multiscale models.

PD1 will perform DFT simulations of Al alloys and subsequent method development of the CE formalism. Benchmark configurations of Al-Mg-Si and Al-Mg-Zn alloys (6xxx and 7xxx series) will be simulated with DFT for producing a total energy database, which will be used for training the CE model and related algorithms. The existing CE software for fixed crystal lattices will be extended to include coordination-dependence (interstitial sites, grain boundaries), strain effects, and magnetism. Different machine learning approaches will be investigated for training the CE model most efficiently. The CE model will be used, e.g., for studying crystal structures, formation enthalpies / free energies, phase diagrams by Monte Carlo methods. The CE energies and DFT migration barriers will be fed into kinetic Monte Carlo (KMC) simulations, which will be used for studying in silicon diffusion, clustering and precipitate formation in the 6xxx-series alloys. At later stages, the same CE methodology will be extended to the 7xxx series. The atomistic CE and MC simulations machinery will be combined seamlessly with multiscale models.

Qualifications

The applicant must have a PhD (or equivalent) in physics, computational materials science or chemistry. He/she has to demonstrate good basic knowledge in solid state physics and quantum physics (chemistry).  A documented background in computational physics/chemistry is required, either with a focus on atomistic modelling (density functional theory and/or molecular dynamics) or dislocation dynamics. The applicant must have good programming skills in at least one of the following programming languages: C/C++, Java, and/or Python. Experience from modelling of metallic microstructures and/or machine learning algorithms will be considered as an advantage.

The successful candidate should be creative, with a strong ability to work problem oriented. He/she should also enjoy interdisciplinary research and take keen interest in learning and working in teams.

The position requires spoken and written fluency in the English language. Applicants from non-English-speaking countries outside Europe must document English skills by an approved test.

Terms of employment

The appointment of the Postdoc will be made according to Norwegian guidelines for universities and university colleges and to the general regulations regarding university employees. NTNU’s personnel policy objective is that the staff must reflect the composition of the population to the greatest possible extent. Female applicants are strongly encouraged to apply.

The position of a post-doctoral researcher is remunerated according to the Norwegian State salary scale. There is a 2% deduction for superannuation contribution.
