Short presentation

My research activities focus mainly on performing analytical calculations and modelling magnetic topological systems for realistic condensed matter applications. In particular, I was involved in predicting the existence of skyrmions in a kagome magnet. We also plan to use these tiny magnetic excitations to perform logical operation in a novel way. In that regards, Magnonics, as a novel research field, represents a hope for building smaller and lower-energy consumption logical devices.

Biography

I am currently working in the department of Physics and Astronomy, Uppsala University as a “Forskare”. I am a group member of the Atomistic Spin Dynamics (ASD) team, a subgroup in the Division of Materials Theory. The research in ASD is mainly devoted to the study and comprehension of the properties of magnetic materials at a very fundamental level. Thus, as the advancement in technology offers new possibilities to perform experimental studies at decreasing length scales and time scales, the importance of the dynamical response of individual atomic spins becomes more and more important. An atomistic spin dynamics method, where the time evolution of atomic spins are studied theoretically by solving the Landau-Lifshitz-Gilbert (LLG) equations, has been developed and has been successfully applied to a number of interesting cases by ASD team. The method has been implemented in a computer code, named UppASD as in Uppsala Atomistic Spin Dynamics, which is available to research groups globally. By combining the spin dynamics simulations with ab-initio calculations based on density functional theory, the ASD team obtain reliable spin models without a priori knowledge of the magnetic properties of the systems studied. From the ab-initio point of view, we have improved the techniques used to calculate the needed parameters for the spin models so that systems with non-collinear magnetic ordering and materials with strong electron correlations can now be treated more accurately.
