Rudolf Feile

Prof. Dr. Rudolf Feile is a Professor in the Department of Physics at Technische Universität Darmstadt, specializing in optical solid-state spectroscopy. His research group employs Raman and Brillouin spectroscopy to investigate excitations in condensed matter systems across diverse energy ranges.

His primary research interests include:

• Optical Spectroscopy
• Solid-State Physics
• Raman and Brillouin Spectroscopy
• High-Temperature Superconductors
• Condensed Matter Physics
• Molecular Magnetism

Prof. Feile's experimental work utilizes advanced instrumentation including a double-grating monochromator for Raman spectroscopy and tandem Fabry-Perot interferometers for Brillouin studies. His group operates Ar-ion and NdYAG lasers, cryostats covering 2.5K–300K temperatures, and diamond anvil cells enabling high-pressure experiments up to 30 GPa. Research spans carbon nanotube composites, high-Tc superconductors, molecular spin transitions, and high-pressure nitrogen studies, with significant contributions to understanding phonon behavior, charge transfer mechanisms, and phase transitions in complex materials.

His publication record (1995–2008) reveals a consistent focus on light scattering phenomena in superconducting superlattices and novel materials, demonstrating expertise in correlating spectroscopic data with fundamental physical properties under extreme conditions.
