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

具有竞争相互作用和各向异性的受抑磁体可以具有拓扑上非平凡的量子基态和自旋激发。我们试图找到和研究模型材料的类强相关氧化物与大自旋轨道耦合，将作为实验实现这一有趣的物理。这包括铱酸盐和铑酸盐Kitaev材料以及在三角形几何形状中具有各向异性磁性的Yb 3+氧化物。该项目将晶体生长和结构表征与多极端条件下的热力学和输运测量相结合，例如非常低的温度，高磁场和高压。

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.
