Research at HFML-FELIX
HFML-FELIX's high-field magnets and free-electron lasers enable scientists to expose matter to extreme conditions and drive it into previously inaccessible states and phases. Our dedicated research groups take full advantage of these possibilities by pushing the boundaries of science with their innovative research projects.
Research groups
HFML-FELIX has a strong in-house research programme subdivided into six accomplished research groups with a focus on the creative use of high magnetic fields, intense infrared and THz free-electron lasers, and the combination thereof to conduct a distinguishing research programme.
Condensed Matter Physics
The Condensed Matter Physics group uses the radiation of free electron laser FELIX to study both static and dynamic properties of matter. The goal of their research is to understand and control the relationship between the properties and structure of nanoscopic and molecular materials, with an emphasis on phenomena that occur on very short time scales. The underlying line is the interaction of photons with matter, the ambition is to achieve full control.
Staff scientists: Andrei Kirilyuk | Joost Bakker | Carl Davies
Correlated Electron Systems
The Correlated Electron Systems group focuses on a variety of topics like unconventional superconductivity, low-dimensional metals, quantum critical phenomena and quantum magnetism. Other topics of interest include magnetization, magnetostriction, thermopower, and the Nernst effect.
Staff scientists: Nigel Hussey
FELIX Infrared and THz Spectroscopy
The FELIX Infrared and THz Spectroscopy group develops and uses mass spectrometric techniques in combination with advanced infrared and terahertz spectroscopy. Their main scientific focus is in the field of astrochemistry, with the aim to understand the chemical evolution in astrophysical environments, such as interstellar star-forming regions or (exo-) planetary atmospheres, by simulating their conditions in the laboratory.
Staff scientists: Britta Redlich | Sandra Brünken
Molecular Structure and Dynamics
The Molecular Structure and Dynamics group combines and integrates mass spectrometry with IR spectroscopy, enabling them to obtain infrared spectral fingerprints for mass-selected ions inside the mass spectrometer. They apply infrared ion spectroscopy in various analytical challenges of identifying molecular structures of low-abundance compounds within complex mixtures, e.g. in biomarker discovery.
Staff scientists: Jos Oomens | Jonathan Martens | Giel Berden
Semiconductors & Nanostructures
The Semiconductors & Nanostructures group mostly studies quantum phenomena and transport in low-dimensional systems like graphene, oxide heterostructures and topological insulators. Other topics of interest include far infrared resonances (cyclotron and spin), and interband magneto-optics.
Staff scientists: Uli Zeitler | Steffen Wiedmann
Soft Condensed Matter & Nanomaterials
The Soft Condensed Matter & Nanomaterials group primarily conducts research on magnetic levitation, the alignment of molecular systems and in situ monitoring of crystal growth. Other topics of interest include chirality and molecular magnetism.
Staff scientists: Peter Christianen | Hans Engelkamp
