FHI Theory

Theory Department

The research in the Theory Department focuses on a quantitative modeling of materials properties and functions, and in particular on processes in working catalysts and energy conversion devices. For this we advance and employ predictive-quality multiscale models, advanced data science techniques and machine learning, thereby straddling the frontiers of physics, chemistry, computing sciences, as well as materials science and engineering.

ASESMA Group Picture

Researcher from the Fritz Haber Institute of the Max Planck Society (FHI) have recently contributed to the 8th African School on Electronic Structure Methods and Applications (ASESMA), held from June 9th to 20th, 2025, at the University of Ghana. more

When Electrons "Jump" into Water: The Secret Behind High Electrode Capacities

In order to develop improved electrolysers for regenerative hydrogen production, the processes on the surfaces of the metal electrodes used must be precisely understood. Researchers from the Theory Department at the Fritz Haber Institute have now been able to show that even the smallest spillover of metal electrons into the aqueous electrolyte environment is sufficient to increase the energy storage capacity more than tenfold. Only if computer simulations take this quantum mechanical effect into account can they be used reliably to investigate promising new electrolyser materials. more

Green Light for e-conversion 2.0

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) announced the renewal of funding for the Cluster of Excellence e-conversion, ensuring its continuation for another seven years starting January 1, 2026. The Fritz Haber Institute of the Max Planck Society is proud to be part of this distinguished and interdisciplinary research network, which drives cutting-edge energy science and fosters vital cross-disciplinary collaboration to tackle the pressing challenges of the global energy transition. more

Revealing Hidden Atomic Movements through Machine Learning

Researchers at the Fritz Haber Institute have developed the Automatic Process Explorer (APE), an approach that enhances our understanding of atomic and molecular processes. By dynamically refining simulations, APE has uncovered unexpected complexities in the oxidation of Palladium (Pd) surfaces, offering new insights into catalyst behavior. more

Not humans or robots, but humans and robots. A perspective for AI-driven self-controlled laboratories of the future

The urgent need for a transition to sustainable energy sources demands a significant acceleration of traditional research and development cycles. Self-driving labs (SDLs), powered by artificial intelligence (AI), could play a pivotal role in this transformation. In a perspective paper in the renowned journal Nature Catalysis, researchers from the Theory Department at the Fritz Haber Institute discuss the role played by humans in future such self-driving labs for catalysis research. more
