Johan Klarbring

Johan Klarbring is an Assistant Professor in the Department of Physics, Chemistry and Biology (IFM) at Linköping University. His research focuses on theoretical material science using ab initio computational methods to study energy materials such as solid oxide fuel cells, batteries, solar cells, and thermoelectric devices. He combines quantum mechanics and statistical physics to analyze phase stabilities and electronic properties of dynamically disordered solids.

His work emphasizes computational approaches to understand material behavior at finite temperatures, including defect formation, ionic transport, and anharmonic effects. Collaborations involve international teams and cutting-edge facilities like supercomputers for large-scale simulations.

Key research themes include perovskite materials, machine learning force fields, and thermoelectric properties. Notable contributions address dynamic nanodomains in perovskites and vacancy-driven ion conduction mechanisms. His group (Ab initio methods and energy materials (TEAM)) explores eco-friendly applications of disordered solid materials.

Recent projects include studies on lead-free perovskites, superionic transitions, and magnetism in halide double perovskites. He has contributed to over 30 peer-reviewed articles, with high-impact work in Nature Nanotechnology and Chemical Science.
