This resource request is aimed at supporting our ongoing efforts in materials discovery and chemistry under extreme conditions. Currently this research is enabled by a medium allocation (NAISS 2024/5-691 80,000 core-h/month), a level we wish to increase slightly. We are mainly focused on two topics: (i) predicting pathways leading to astrochemically relevant materials and (ii) predicting novel properties of materials under high-pressure. The properties we are exploring include, but are not limited to, new polarity inverted bonds and metal-organic superconductors. To this end, we are screening large numbers of structures and reaction pathways using structure search algorithms coupled to quantum chemical methods. Computationally demanding quantum chemical methods are required to obtain accurate predictions of structure, stability, reaction kinetics and thermodynamics.
