Recent studies of the electronic excited states of materials have led to the discoveries of rich and fascinating phenomena that are distinct from those in the ground state. Various theoretical and computational methods have been developed and utilized to understand material properties in excited states, which reveal a number of highly interesting physical effects with diverse potential technological applications. Examples include various excitonic effects in transition metal dichalcogenide (TMD) systems (including moiré minibands for the excitons in aligned TMD heterostructures) and magneto-optical responses in van der Waals magnets.

This symposium aims to bring together materials scientists and condensed matter physicists who develop and combine various theoretical and computational approaches to study materials in their electronic excited states. Abstracts are solicited in the areas of methodology development and material applications. The category of theoretical and computational methods includes modelling of electronic excited states, ab initio methods, computational spectroscopy, etc. The category of material systems includes bulk semiconductors, polymers and perovskites, as well as topological insulators, van der Waals crystals (e.g., transition metal dichalcogenides, 2D magnets), and one-dimensional materials (e.g., carbon nanotubes).
