About the Project

Department name: Business, Technology and Engineering/Materials and Engineering Research Institute

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. The modeling group within the Materials and Engineering Research Institute has extensive experience in computational modelling and the research group of Dr Ostler has extensive knowledge of theoretical and computational magnetism.

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.
