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.

Magnets for a Cleaner Future: ERC Synergy Grant Funds MAGNESIS to Unlock Magnetically Enhanced Catalysis

Prof. Karsten Reuter, Director of the Theory Department at the Fritz Haber Institute of the Max Planck Society and a leading catalysis expert, has been awarded one of the 66 prestigious ERC Synergy Grants for “MAGNESIS—Magnetically Enhanced Electrocatalysis,” together with Prof. Galán-Mascarós (ICIQ, Spain), Prof. Jeppe V. Lauritsen (Aarhus University, Denmark), and Prof. David Écija (IMDEA Nanoscience, Spain). Over the next six years, the €12 million project will uncover how magnetic fields can help to drive electrochemical reactions more efficiently—from studying what happens at the atomic level to testing complete devices such as fuel cells and electrolyzers. more

When Code Meets Quantum: how Students from the Berliner Hochschule für Technik Helped Redesign a Research Tool

What happens when you pair sharp programming minds with complex quantum chemistry challenges? At the Fritz Haber Institute (FHI), that mix just produced something exciting: an interactive visualization platform that helps scientists see and manage how they improve simulations of electronic properties of materials. more

Four scientists from the Fritz Haber Institute attended the 74th Lindau Nobel Laureate Meeting in Chemistry, held from June 29 to July 4, 2025. The event featured 33 Nobel Laureates and over 600 young scientists worldwide. more

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
