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

Interviews are scheduled for: week commencing 13th July 2020.

For information on how to apply please visit https://www.shu.ac.uk/research/degrees Your application should be emailed to meri-student@shu.ac.uk and cc in t.ostler@shu.ac.uk by the closing date of 1 July 2020.

Funding Notes

The PhD studentship provides tuition fees at UK/EU levels and a maintenance bursary at the UK Research Councils’ national minimum doctoral stipend rate (£15,285 for 2020/21). The scholarship is available for three years of full-time or five years of part-time study (paid at 50%)

Current Research in magnetism (CRIM) 2019

This year sees the return of the CRIM series in a different format to previous years highlighting current ‘hot topics’ in the field of magnetism. This year the theme is recent advances in antiferromagnetism. The one day conference will be held at the new IOP building, which is less than a 5 minute walk from Kings Cross, which is a great opportunity to see the new home of the IOP and what it has to offer.

Due to support from the IOP Magnetism Group and the Collaborative Computational Project on Magnetism (CCP-Mag) the event is free to register for IOP members and just £25 for non-members. Lunch and refreshments will be provided and there will be a mix of invited and contributed talks along with posters during lunch. Registration is now open at this link and abstract submissions are being accepted (see link here).

There are three confirmed invited speakers from the UK and Europe covering both experimental and theoretical advances in the field. The three invited speakers are:

  • Chiara Cicarelli, University of Cambridge, UK
  • Tomas Jungwirth, Academy of Sciences of the Czech Republic, Czech Republic
  • Eduardo Tapia, Peter Grünberg Institute (PGI), Germany
