Seminar ÚFKL: Jaroslav Tóbik

Department of Condensed Matter Physics (ÚFKL) invites you to lecture

Jaroslav Tóbik (Institute of Electrical Engineering, Slovak Academy of Sciences, Bratislava): Micromagnetism at IEE SAS

In this seminar, I will give a short introduction to the topic of micromagnetism. First, I will mention the typical problems associated with this topic that we solved at our institute - IEE SAS. Then, I will give a short introduction to the physical model of micromagnetism. Finally, I will come to the main topic of the seminar - a phenomenon we observed in numerical simulations - the dynamical breaking of symmetry in magnetic systems. Along the micromagnetism, I will also mention the metadynamics algorithm, which is a variant of optimization methods that can also be used in other areas of computer simulations.
