Ralph Ernstorfer

Prof. Dr. Ralph Ernstorfer is a leading physicist holding dual appointments at the Technical University Berlin (Professor, Institute for Optics and Atomic Physics) and the Fritz Haber Institute of the Max Planck Society (Group Leader, Department of Physical Chemistry). His career includes tenure as a Max Planck Research Group leader (2010–2017) and W2 scientist (2017–2021) at FHI. He specializes in ultrafast dynamics of quantum materials, with affiliations spanning TU Berlin, Max Planck Institutes, and international collaborations.

His research explores electron-phonon interactions, topological materials, and surface dynamics using advanced spectroscopic methods. Key themes include:

• Ultrafast electron and lattice dynamics in 2D systems (e.g., bismuthene, black phosphorus)
• Singlet fission mechanisms in organic semiconductors
• Non-equilibrium phenomena in ferromagnets and ferroelectrics
• Development of time-resolved photoemission techniques

Recent publications (2019–2025) demonstrate prolific output in high-impact journals, focusing on momentum-resolved spectroscopy, phonon scattering, and computational materials science. His lab pioneers methodologies for studying energy flow in solids at femtosecond timescales.

Prof. Ernstorfer advises researchers at the Fritz Haber Institute and TU Berlin, though specific student names are not listed. His group maintains active instrumentation development for ultrafast experiments, including momentum microscopes and spectral analysis tools.
