Excited-state Dynamics and the Role of Electron-Phonon Interactions in Quantum Materials

Integrated architectures at the atomic-scale can be achieved via 2D materials and their corresponding van der Waals heterostructures with deterministic defect engineering. In this talk I will show several examples of ab initio designed quantum materials via an understanding of the electron-phonon interactions in these. I will demonstrate our new carrier lifetime-driven approach to materials with an ab initio description of electron-phonon and electron-optical interactions in a Feynman diagram many-body framework integrated with a nonequilibrium carrier transport theory method. Finally, I will give an outlook on theory-directed control of excited state and non-equilibrium phenomena to deliver integrated quantum-engineered materials with diverse applications in quantum information science as well as quantum sensing and metrology.
