Topological excitations for emergent computing devices

Atomically small topological excitations (TE): domain walls, vortices, and skyrmions can be used as memory units in neuromorphic computing. Study of TE in functional oxides can emulate the dynamically learning interconnects in brains.  Using numerical modelling and working in close collaboration with experimentalists of the Consortium, ESR will simulate the dynamics of TE to optimize them for information processing. ESR will perfection her/his skills in computational methods and high-performance computing, coupled with output from theoretical physics, Landau functional, and elasticity theory, applied to the experimental environment of material physics. The main part of research will be performed at University of Picardie, France. Additionally, the ESR will spend the secondments at University College London, United Kingdom for Modeling of the M-I materials (1 Month) and at IBM Research –

Zurich, Swittzerland to Exchange knowledge on simulation strategies (0.5 Month).
The University of Picardie is a young developing French University, created in 1970 and having approximately twenty thousand students. The faculties are Science, Low, Arts, and Medicines. Development of Material Science researches and corresponding MSc and Ph.D. training is one of the priorities of University and Province of Picardy.  Principal expertise of the Physics Department is the study of epitaxial films of multifunctional oxides. The theory group provides theoretical and numerical modelling of nanoscale ferroelectrics and multifunctional materials for potential application. Equipment: a distributed memory calculator: 1680 compute cores, the computing power of 7.1904 teraflops, 12.3 TB of memory – Intel (R) Xeon.
