Abstract Scope |
Developing accurate models of material responses to intense radiation is crucial for creating radiation-resistant materials and precise materials manipulation at the atomic level, including in the excited electronic state. These models must account for rapid quantum interactions immediately post-irradiation, linking initial excited states to longer-term radiation effects. In this talk I will present my group’s work on generalizing accurate quantum mechanical modeling of electronic stopping using real-time time-dependent density functional theory towards a cost-effective computational description of electronic stopping as ions travel through materials: With little loss of accuracy, we train a machine learning model on high-fidelity quantum mechanical simulation data of electronic stopping. With this approach we aim for multi-scale ion beam modification modeling and show that the million-fold reduced computational cost allows for first-principles Bragg peak simulations. |
