Solitary waves and dispersive hydrodynamics on the nanoscale for next generation storage and logic applications

Research Project, 2015 – 2017

The field of spintronics has been at the forefront of information and communications technology (ICT) for the past 30 years and today continues to push the boundaries of next-generation technologies. Recent global efforts are focused on the smallest objects in magnetic materials: solitary waves. These have ideal features and can exhibit exceptional stability. However, the current understanding of solitary waves, based on a 2D simplification, is not compatible with realistic 3D materials, impeding an accurate interpretation of the results and the development of novel applications. This project will focus on the study of magnetic solitary waves, specifically the effects of dimensionality and spatially inhomogeneous fields. The project is divided in two stages. Firstly, the existence of solitary waves and their dynamics will be studied analytically by setting a nonlinear boundary value problem. Special emphasis will be given to a solitary wave known as dissipative droplet. In order to consider more realistic effects, numerical methods will be used and developed, with the aim of providing accurate and fast results. Secondly, fundamental solitary waves will be analytically studied by linking magnetism to the field of dispersive hydrodynamics and the world-renowned ultra-cold atomic research at the University of Colorado. This project will be enriched by an interdisciplinary environment and will be of great significance to both the fundamental and experimental communities.
