Topological Quantum Phases in Correlated Electron Systems with Large Spin-Orbit Coupling (E06)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2015 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 107745057

Frustrated magnets with competing interactions and anisotropies can host topologically non-trivial quantum ground states and spin excitations. We seek to find and investigate model materials in the class of strongly correlated oxides with large spin-orbit coupling that will serve as experimental realizations of this intriguing physics. This includes iridate and rhodate Kitaev materials as well as Yb3+ oxides with anisotropic magnetism in the triangular geometry. The project combines crystal growth and structural characterization with thermodynamic and transport measurements under multiextreme conditions such as very low temperatures, high magnetic field and high pressure.
