Excited-state processes are essential for emerging applications in materials, from energy conversion to quantum information science. The associated generation and relaxation mechanisms are often coupled to quantum selection rules, stemming from the underlying material structure. In this talk, I will discuss the relation between excited-state evolution and structural design in low-dimensional semiconductors. I will present our band-structure theoretical and computational approaches to calculate phonon-assisted exciton interaction dynamics as a function of the underlying structure and discuss the importance of many-body effects in the excited-state relaxation and dephasing mechanisms. I will further discuss our ab initio–based data-driven approaches to explore excited-state relaxation, offering new design principles to achieve light-induced quantum coherence in semiconducting materials.
