postdoc position

We are looking for a Postdoctoral Researcher to join the group!

The successful applicant will work on the EPSRC-funded TERASWITCH project (Towards Low Dissipation THz-Induced Switching of Magnetic Materials) and will develop theoretical models of key magnetic materials using computational methods in condensed matter and magnetism.

The role will involve working with Science and Technology Facilities Council to perform and analyse the results of first principles calculations that will feed into atomistic spin dynamics models. You will be expected to be confident with HPC systems, develop code and run first principles and atomistic codes. This work will also be carried out in collaboration with experimental groups in Germany. You will be expected to promote our work at conferences and workshops and contribute to the generation of publications and external funding bids.

You must have a PhD (or about to complete) in theoretical magnetism/condensed matter physics and have expertise in Mathematical Physics. Experience in computational condensed matter and in programming (C/C++, FORTRAN) is essential. The Ability to work effectively both independently and collaboratively, both on projects and as part of a team is also essential.

We particularly welcome applicants from underrepresented groups

For non-EU applicants, we are unlikely to be able to offer a certificate of sponsorship for this job (unless you are switching from a UK student visa), so you should only apply if you already have unrestricted permission to work in the UK.

For full information, see https://www.jobs.ac.uk/job/CAM894/postdoctoral-researcher-theoretical-modelling-of-terahertz-spin-dynamics .  For informal enquiries, please feel free to contact Tom Ostler: t.ostler@shu.ac.uk.  Application deadline: 12 July 2020.

We welcome applications for job-share, part-time and flexible working arrangements

Modeling Ultrafast THz-Induced Magnetisation Dynamics for Next Generation Data Storage and Processing

Project Description:
Research Area: Since the pioneering work of Beaurepaire and co-workers in 1996 [1], the field of ultrafast spin dynamics has rapidly developed. The ability to use femtosecond laser pulses to not only quench magnetic order, but reverse [2] and control it has opened up new possibilities for magnetic data storage and information processing. More recently, with recent advances in experimental methodology and the need for low-power future information technologies, there has been huge interest in the area of using finely tuned laser pulses with frequencies of light in the terahertz regime.

The aim of this PhD will be to develop models of terahertz-induced spin dynamics based on a multi-scale approach. The successful candidate will use state-of-the-art density functional theory methods alongside atomistic spin dynamics [2] to simulate the dynamics of complex magnetic materials after excitation with a terahertz laser pulse. He/she will work alongside a postdoctoral researcher and a senior scientist at the Science and Technologies Facilities Council working on the EPSRC project, TERASWITCH, to support his/her research and will be supported by experimental measurements through collaborations with the Free University in Berlin.

We are seeking a highly motivated graduate in physics, engineering or mathematics with experience in programming and strong mathematical skills. Knowledge of condensed matter physics and/or magnetism and magnetic materials, as well as knowledge of methods in computational magnetism/condensed matter (e.g. density function theory, monte-carlo methods), is desirable but not essential.

Application deadline: 12 noon 1st July 2020
We strongly recommend you contact the lead academic, Thomas Ostler t.ostler@shu.ac.uk to discuss your application

Start date for studentship: Enrolment in September 2020

PhD Studentships Available at Sheffield Hallam

The Materials and Engineering Research Institute (MERI) at Sheffield Hallam University is funding 2 Graduate Teaching Assistant PhD studentships on any topic in materials and engineering, physics and mathematics. This is a competitive process, whereby applications from students are made with the support of an academic at Sheffield Hallam. A short proposal of the work during the PhD is required and can be done in collaboration with the academic. Potential projects in the areas of computational magnetism are:

  • Ultrafast spin dynamics in systems with emergent phenomena – involving a multiscale approach, combining first and second principles modeling.
  • Low energy control of magnetism in complex magnetic materials – using a range of approaches to simulate the dynamics of advanced functional materials to find new materials and routes towards low energy devices.

Potential projects are not limited to those described above. If you have a specific project in mind or if you require more information on these potential projects, please get in touch by email.

The deadline for applications is 1st Febrary 2018, see this link for more details on the application process and eligibility criteria.
