Research Interests

Quantum magnets serve as ideal testing grounds for many-body quantum physics. The research in this field is propelled like a ping-pong ball between theory and experiment; either theoretical predictions are tested with experiment or surprising experimental observations call for new theory. In the Quantum Magnetism group, such model compounds are investigated experimentally. Their 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 these 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 manipulate them.
