PhD Position: Order-from-Disorder in Frustrated Quantum Magnets ETH Zürich in Switzerland

The Neutron Scattering and Magnetism Group at the Physics Department of ETH Zürich is offering a PhD position focused on the experimental investigation of frustrated quantum magnets. This research explores geometric frustration in quantum systems, which leads to competition between novel collective spin states such as topological structures, quantum spin liquids, multipolar ordered phases, and spin-supersolids. These states are characterized by unique elementary excitations, often with no semi-classical analogues, and their emergence is governed by mechanisms known as thermal and quantum order-from-disorder.

The successful candidate will experimentally control these mechanisms in carefully selected prototypical magnetic materials. The project involves synthesis and growth of single crystal samples, characterization using X-ray diffraction, optical spectroscopy, and a range of magnetothermodynamic, magnetomechanical, and magnetoacoustic measurements at millikelvin temperatures and high magnetic fields. Advanced studies will be conducted using neutron scattering, ultra-high-field, and muon spin rotation techniques at leading user facilities in Switzerland, France, Germany, UK, Japan, and the USA. Data analysis and modeling will be performed in collaboration with theoretical and numerical research groups.

Applicants should have a strong background in laboratory work and experimental data analysis, as well as a solid theoretical foundation in quantum mechanics, statistical physics, and quantum solid-state physics. Good computer skills are a plus, and no prior experience in neutron scattering is required. The candidate is expected to be actively involved in all phases of the project and to take initiative whenever possible.

ETH Zürich offers a stimulating research environment, professional development opportunities, and numerous benefits including public transport season tickets, car sharing, sports facilities, childcare, and attractive pension plans. The university values diversity, sustainability, and equality of opportunity, fostering an inclusive culture and climate-neutral future.
