PhD Position: Order-from-Disorder in Frustrated Quantum Magnets

100%, Zurich, fixed-term

The Neutron Scattering and Magnetism Group at the Physics Department of ETH Zurich is seeking a dedicated candidate for a PhD position focused on experimental investigations of frustrated quantum magnets using neutron scattering and other advanced techniques.

Geometric frustration in quantum systems leads to a competitive emergence of innovative collective spin states, including topological structures, quantum spin liquids, multipolar ordered phases, and spin-supersolids. Each of these states features unique elementary excitations that often lack analogues in classical physics.

The outcome of this competition is typically governed by mechanisms such as thermal and quantum order-from-disorder. Mastering these mechanisms presents an opportunity to manipulate and explore these exotic systems. The successful candidate will implement this control experimentally with a selection of prototypical magnetic materials.

Job Description

• The candidate will engage in the synthesis and growth of single crystal samples, alongside their characterization through X-ray diffraction.
• Further characterization will be performed through optical spectroscopy experiments, as well as magnetothermodynamic, magnetomechanical, and magnetoacoustic measurements at millikelvin temperatures and high magnetic fields, utilizing the advanced equipment in our laboratory.
• The research will culminate in neutron scattering, ultra-high-field, and muon spin rotation studies at leading large-scale user facilities across Switzerland, France, Germany, the UK, Japan, and the USA.
• Data analysis and modeling will be conducted in collaboration with research groups specializing in theoretical and numerical calculations.

Candidate Profile

• The ideal candidate is expected to participate actively in all project phases and to take a leadership role whenever possible.
• No prior experience in neutron scattering is necessary; however, a robust background in laboratory work and analysis of experimental data is essential.
• A solid theoretical foundation in quantum mechanics, statistical physics, and quantum solid-state physics is mandatory due to the complex nature of the project.
• Proficiency in computer skills will be considered an advantage.
