Materials Informatics and Quantum Matter

High-throughput calculations using first-principles methods in combination with approaches from data mining and machine learning fields have enabled a new stage in accelerated discovery of functional materials with special properties. I will present newly developed Organic Materials Database (OMDB, https://omdb.diracmaterials.org/) and discuss use of these methods. Our platform hosts thousands of electronic structures of synthesized organic materials [1] and is a useful tool in searching for novel materials. I will also discuss the implemented tools to predict and search magnetic structure factors and exchange coupling of organic materials in our database. Our work is a step towards a new way to search for novel functional materials characterized by a specific pattern in their electronic structure, for example, Dirac materials, topological insulators [2,3]. I will also present the ongoing work on the dynamics of quantum matter, where we predict transient collective instabilities in driven quantum systems [4].
