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

100%, Zurich, fixed-term

The Neutron Scattering and Magnetism Group, Physics Department, ETH Zurich, is currently looking to fill a PhD position on experimental studies of frustrated quantum magnets using neutron scattering, μSR and other techniques.

Geometric frustration in quantum systems leads to a tight competition between qualitatively new collective spin states, such as topological structures, quantum spin liquids, multipolar ordered phases and spin-supersolids, to name only a few. Each state is characterized by its own set of elementary excitations that often have no analogue in semi-classical physics.

The winner of this competition is usually determined by mechanisms known as thermal and quantum order-from-disorder. Controlling these offers a way to manipulate and study such exotic systems. The successful candidate will realize this control experimentally in carefully selected prototypical magnetic materials.

Job description

  • The work will involve synthesis and growth of single crystal samples, as well as their characterization with X-ray diffraction
  • The samples will be further characteried with optical spectroscopy experiments, as well as magnetothermodynamic, magnetomechanical and magnetoacoustic measurements at mK-temperatures and high magnetic fields, using equipment available in our laboratory 
  • The research will culminate in neutron scattering, ultra-high-field, and muon spin rotation studies at state of the art large-scale user facilities in Switzerland, France, Germany, UK, Japan and the USA
  • Data analysis and modeling will be done in collaboration with research groups that specialize in theoretical and numerical calculations

Profile

  • The successful candidate is expected to be actively involved in every phase of the project and to take the lead whenever possible
  • No prior experience in neutron scattering is required, but a solid background in laboratory work and analysis of experimental data is a must
  • Since the project is based around rather complex concepts in modern physics, a solid theoretical background in quantum mechanics, statistical physics and quantum solid state physics is absolutely essential
  • Good computer skills are a plus

Workplace

We offer

  • Your job with impact: Become part of ETH Zurich, which not only supports your professional development, but also actively contributes to positive change in society
  • You can expect numerous benefits, such as public transport season tickets and car sharing, a wide range of sports offered by the ASVZ, childcare and attractive pension benefits
