Our group works in the field of experimental condensed matter physics with particular focus on magnetism. Our expertise lies in using neutron scattering techniques in combination with magnetic fields and pressures to investigate how magnetic moments (spins) interact in a material. The collective behavior of such systems may result in intriguing quantum states and phenomena of fundamental interest but also with potential applications in quantum technology. The goal is to understand how these states are formed and how to tailor them.
Physical Review B
Abstract: Fractionalization remains one of the most fascinating manifestations of strong interactions in quantum many-body systems. In quantum magnetism, the existence of spinons—collective magnetic excitations…
Journal of Magnetism and Magnetic Materials
Abstract: Demagnetization factors play an important role in micromagnetics modeling but exact solutions only exist for a limited number of particle shapes. Here we use a Fourier space based approach coupled to…
Review of Scientific Instruments
Abstract: The simultaneous application of high magnetic fields and high pressures for controlling magnetic ground states is important for testing our understanding of many-body quantum theory. However, the…
Nature Communications
Abstract: In quantum magnetic materials, ordered phases induced by an applied magnetic field can be described as the Bose-Einstein condensation (BEC) of magnon excitations. In the strongly frustrated system…

Abstract: Quantum magnetic materials can provide explicit realizations of paradigm models in quantum many-body physics. In this context, SrCu2(BO3)2 is a faithful realization of the Shastry-Sutherland model for…
Nature Communications
Abstract: Quantum fluctuations in low-dimensional systems and near quantum phase transitions have significant influences on material properties. Yet, it is difficult to experimentally gauge the strength and…
Chemistry of Materials
Abstract: Quantum spin liquids are highly entangled magnetic states with exotic properties. The S = 1/2 square-lattice Heisenberg model is one of the foundational models in frustrated magnetism with a…
Physical Review B
Abstract: We investigate the magnetic structure and magnetoelectric(ME) effect in the high-field phase of the antiferromagnet LiFePO4 above the critical field of 31T. A neutron diffraction study in pulsed…
Physica B: Condensed Matter
Abstract: The authors regret that there is an error in the units of the fitted slopes giving the magnetoelectric coefficients in Fig. 5. The unit shown is pm/s but should be ps/m. The authors would like to…
