Matthias Dietrich Frontzek

Matthias Dietrich Frontzek serves as an Instrument Scientist at the WAND² diffractometer within Oak Ridge National Laboratory's High Flux Isotope Reactor (HFIR). He concurrently leads the HFIR Beryllium Reflector Replacement project as matrixed scientist, chairs the high-temperature-sample-environment committee, and participates in the US-Japan cooperative neutron scattering research program.

His academic foundation includes a Diploma (MS) in Physics from Technical University Dresden (2003) and a PhD in Physics from the same institution (2009), where his thesis on R2PdSi3 magnetic properties utilized neutron scattering at Helmholtz-Zentrum Berlin under Michael Loewenhaupt.

Frontzek's research specializes in neutron scattering investigations of quantum magnetic phenomena, with emphasis on frustrated spin systems, topological materials, and rare-earth compounds. His work reveals intricate magnetic structures in kagome/hyperkagome lattices, Dirac/Weyl semimetals, and skyrmion-hosting materials, leveraging diffraction techniques to probe phase transitions and collective excitations at atomic scales.

Recent publications demonstrate a concentrated focus on emergent quantum states where geometric frustration intersects with topological band structures. Key trends include van Hove singularity-driven spin density waves, skyrmion stabilization mechanisms in centrosymmetric materials, and quantum criticality in geometrically frustrated magnets, with neutron diffraction serving as the primary investigative tool across these diverse material systems.

His scientific recognition includes:

• PSI Fellow at Paul Scherrer Institut

Frontzek directs major infrastructure initiatives including the HFIR Beryllium Reflector Replacement project critical for reactor longevity and chairs the high-temperature-sample-environment committee supporting advanced user experiments. His international collaboration through the US-Japan program facilitates cross-continental neutron research, while instrument development efforts like ANDiE (Autonomous Neutron Diffraction Explorer) implement machine learning for real-time experimental optimization.

Operating within ORNL's Powder Diffraction Group of the Diffraction Section, Frontzek manages the WAND² instrument user program that serves global researchers studying magnetic and structural properties of quantum materials through neutron powder diffraction techniques.
