Abstract
Machine-learning interatomic potentials (CMD) and density-functional ab initio molecular dynamics (AIMD) are used to investigate the mechanical properties and phase stability of novel high-entropy ceramics and superlattice structures up to temperatures (>1000 K) or relevance for practical uses. The project is a theoretical-experimental collaboration between LiU, TUWien (Austria), Comenius University (Slovakia) and University of California San Diego and includes a large part of activities of FunMat II consortium.
The theoretical investigations are based on methods developed by the PI. Financial support --> personal PI grants: VR Project Grant 2025-04266; and VR Starting Grant 2021-04426. In addition, the research is financed through the VR project grant 2024-04996 (PI G. Ramanath), of which I am co-applicant, and the Competence Center Functional Nanoscale Materials (FunMat-II, Vinnova Grant No. 2022–03071), which has been extended until November 2027. The project is also supported by Olle Engkvist Foundation, Austrian Academy of Sciences, ÖAW, via the DOC fellowship, KUWI grant from TU Wien, Hertha Firnberg Programme.
During 2023-present, we published 21 papers in high-quality journals including Nature Synthesis, Science Advances, Nature Communications, Physical Review Materials, Acta Materialia, and npj Computational Materials. NAISS resources are acknowledged in all publications (see activity report).
