Dr. Ferdi Aryasetiawan

Biography

Ferdi Aryasetiawan is a Professor in Mathematical Physics at Lund University. His research focuses on the theoretical methods for calculating the Green functions of many-electron systems, which are indispensable in condensed matter physics for understanding fundamental physical properties such as one-particle excitations, measured photoemission and inverse photoemission. His work also involves a wide range of theoretical frameworks including many-body perturbation theory, Hedin's GW approximation, and dynamical mean-field theory (DMFT). Aryasetiawan has contributed significantly to the field by developing new methodologies to calculate the electronic structure of strongly correlated materials, which are notoriously challenging to describe accurately using standard techniques like density functional theory (DFT). He has published numerous articles discussing the intricacies of electronic interactions in complex materials, aiming to bridge gaps between existing theoretical approaches and real material properties. His contributions have enhanced the understanding of spectral functions and electronic states in various materials, particularly those containing transition metals and lanthanides. Throughout his career, Aryasetiawan has been involved in collaborative efforts, combining techniques such as GW + DMFT, which has proven successful in analyzing strongly correlated electron systems.
