Overview

Ab initio computational approaches for quantum dynamics of electrons in molecules, nanostructures, and solids have been rapidly developing across physics, chemistry, optics, and materials science. The 2nd International Symposium on Ab Initio Electron Dynamics Simulations (AIEDS2) will provide an international forum for researchers working in these fields. The symposium will address a broad range of theoretical and computational approaches, including time-dependent density functional theory (TDDFT), ground- and excited-state density functional theory (DFT), and related ab initio and model-based methods for electron dynamics, as well as their applications to fundamental quantum dynamics, ultrafast laser phenomena, optical properties, and materials design. We expect AIEDS2 to bring together researchers who are actively advancing electron dynamics simulations and related areas, to promote the exchange of research and ideas.

The program will also include a special session featuring Q-LEAP ALICe (Advanced Laser Innovation Center) Project. This session will highlight invited talks on attosecond science and smart laser materials processing, providing a unique opportunity to connect cutting-edge experimental advances with ab initio simulations.

AIEDS2 will be held over five days. The first two days will be devoted to a school, offering lectures on electron dynamics theories and hands-on tutorials using the ab initio program package SALMON on a supercomputer system. The following three days will consist of the workshop, where invited and contributed presentations will showcase the latest progress and explore future directions in the field.
