Jan Rusz

Jan Rusz is Professor at the Department of Physics and Astronomy, Uppsala University, specializing in Materials Theory. His research focuses on theoretical aspects of electron microscopy, magnetism, and electronic structure of materials, with particular emphasis on advanced spectroscopic techniques and their theoretical foundations.

His primary research interests include:

• Theory of inelastic electron scattering and dynamical electron diffraction
• Electron energy loss near-edge structure (ELNES) and electron magnetic circular dichroism (EMCD)
• X-ray and optical spectroscopies including XMCD, Kerr effect, and Faraday rotation
• Electronic structure calculations of strongly correlated electron systems
• Magnetism, magneto-crystalline anisotropy, and exchange interactions
• Theory of two-dimensional angular correlation of electron-positron annihilation radiation

Professor Rusz's recent publications demonstrate a strong focus on advancing electron microscopy techniques for atomic-scale magnetic and vibrational measurements. His work bridges theoretical modeling with experimental applications, particularly in developing methods to visualize magnetic moments and phonon modes at unprecedented resolution. His research has appeared in top-tier journals including Nature, Nature Materials, and Physical Review Letters, reflecting significant impact in the field of materials physics and electron microscopy.

His research group appears to collaborate extensively with experimentalists to develop and validate new methodologies in electron microscopy, particularly for measuring magnetic properties at the nanoscale and atomic scale. The work has implications for developing new magnetic materials and understanding fundamental aspects of magnetism in condensed matter systems.
