Bernhard Keimer

Bernhard Keimer is a distinguished physicist and Director at the Max Planck Institute for Solid State Research in Stuttgart, Germany. He holds dual academic appointments as Honorary Professor at the University of Stuttgart and Adjunct Professor at the University of British Columbia. As a leading researcher in condensed matter physics, he directs the Solid State Spectroscopy department which focuses on experimental investigations of quantum materials using advanced spectroscopic techniques.

His academic journey began with a pre-diploma in Physics from the Technical University of Munich in 1985, followed by a Ph.D. in Physics from the Massachusetts Institute of Technology in 1991 under the supervision of Prof. R. J. Birgeneau. His career trajectory includes progressive faculty positions at Princeton University, where he served as Assistant Professor (1992-196), Associate Professor (1996-1997), and Full Professor (1997-1998) of Physics.

Professor Keimer's research centers on strongly correlated electron systems, with particular emphasis on quantum materials exhibiting exotic electronic and magnetic phenomena. His department employs a sophisticated array of experimental techniques including neutron and X-ray diffraction and spectroscopy, optical spectroscopy, and Raman scattering to probe the structure and dynamics of these complex materials. A distinctive feature of his research program is the close collaboration between experimentalists and theorists within the department, recognizing that theoretical insights are essential for interpreting complex experimental data in this field. His work has significantly advanced our understanding of high-temperature superconductivity, quantum magnetism, and emergent phenomena in transition metal oxides.

Analysis of Professor Keimer's recent publication record reveals a consistent focus on cutting-edge investigations of quantum materials, particularly transition metal oxides. His research increasingly explores the intersection of spin, orbital, and lattice degrees of freedom in correlated electron systems. Recent work has made significant contributions to understanding spin-orbit excitons, terahertz magnonics in antiferromagnetic materials, and the electronic structure of novel superconducting materials including nickelates and ruthenates. His publications span high-impact journals including Nature family journals, Physical Review Letters, and Science, demonstrating both the breadth and significance of his research contributions.

Professor Keimer has received numerous prestigious awards that recognize his outstanding contributions to condensed matter physics:

• 2024: ERC Advanced Grant "SpecTera" for terahertz magnonics research
• 2022: Kamerlingh Onnes Prize for pioneering contributions to the understanding of quantum materials
• 2022: Mahendra Lal Sircar Lecture
• 2015: ERC Advanced Grant "Com4Com"
• 2011: Gottfried Wilhelm Leibniz Prize from the German Research Foundation
• 1995: David & Lucille Packard Faculty Fellowship
• 1996: Alfred P. Sloan Faculty Fellowship

He has also been consistently recognized as a Highly Cited Researcher in Physics or Cross-field categories from 2014-2022.

Professor Keimer has played a significant role in mentoring and advising the next generation of scientists. As Chair of the International Max Planck Research School on Condensed Matter Science since 2001, he has overseen the training of approximately 100 graduate students at the MPI for Solid State Research and the University of Stuttgart. He also chairs the Max Planck Graduate Center for Quantum Materials, which supports around 60 graduate students across multiple locations in Germany. His leadership extends to numerous research grants, including two ERC Advanced Grants that have enabled the development of cutting-edge experimental instrumentation for inelastic X-ray scattering and terahertz magnonics.

The Solid State Spectroscopy department under Professor Keimer's leadership operates as an integrated research unit that combines experimental and theoretical approaches. The department maintains close collaborations with the Crystal Growth Scientific Facility, Quantum Materials Department, and Stuttgart Center for Electron Microscopy at the Max Planck Institute. Notably, Professor Keimer co-directs the Max Planck Society - University of British Columbia - University of Tokyo Center for Quantum Materials, establishing an international research network that facilitates collaborative studies and annual workshops at alternating locations. This global research infrastructure enables comprehensive investigations of quantum materials across multiple experimental techniques and theoretical frameworks.
