The Group
This is the home of Prof. Dr. Andrey Zheludev's Neutron Scattering and Magnetism Group in the Laboratory for Solid State Physics at ETH Zürich. AZ's lepidopteraweb pages can be found here.
A key theme in modern solid state physics is the emergence and competition of novel collective quantum phases and excitations in strongly correlated electrons materials. The main focus of the Neutron Scattering and Magnetism group is the use of state-of-the-art quantum beam technologies at large scale facilities and complementary in-house measurements for a fundamental experimental study of these phenomena in prototype compounds.
Our focus is on quantum magnetism of insulators. We study exotic orders in frustrated spin systems (spin-nematics, spin density waves, chiral phases, etc.), spin liquids, Bose-Einstein condensation of magnons and magnon "molecules", universality and scaling at quantum phase transitions, and the effects of disorder and other topics.
Our research starts at the ETH Hönggerberg campus, where we synthesize and characterize unique single crystal samples of quantum magnetic materials and investigate them with laboratory-based techniques, such as high resolution optical spectroscopy, very low temperature magnetometry, electrometry and calorimetrey, as well as diamond-anvil high pressure experiments. Our studies culminate in neutron diffraction and spectroscopy, muon and ultra high field experiments at user facilities around the globe.
