Title: Engineering Quantum States in Atomically Thin Materials

Speaker: Dr. Shivangi Shree, Harvard University

Abstract: Atomic monolayers, which consist of a single layer of atoms, exhibit distinct physical properties compared to their parent bulk materials. Examples such as graphene, and monolayers of materials like MoS2, which have gained immense attention due to their unique properties and potential applications in the fields of electronics and optics. These monolayers also give access to new degrees of freedom of the electronic system (such as the valley index) or interactions between quasiparticles such as excitons (Coulomb–bound electron-hole pairs). In this seminar I will discuss how our understanding and engineering of exciton states in multi-layers enables us to finely tune the linear and non-linear optical properties of atomically thin materials.
