Abstract
I present a fully ab initio scheme to model transient spectroscopy signals in the presence of strongly bound excitons. Using LiF as a prototype material, I show that the scheme is able to capture the exciton signature both in time-resolved angle-resolved photoemission spectroscopy and transient absorption experiments. The approach is completely general and can become the reference scheme for modeling pump and probe experiment in a wide range of materials.
