Quantum-coherent transport in low-dimensional mesoscopic structures and thin films
… two, quite different, materials system: bismuth iridate thin films, and Ge/AlAs heterostructures on GaAs or Si substrates. Both materials are of interest for future quantum technologies and devices. Measurements in bismuth iridate thin films reveal interesting transport characteristics such as …

Beyond the isotropic two-dimensional Heisenberg model: Raman scattering studies of the transition between isotropic and anisotropic spin dynamics in Sr2IrO4
… regarding strong spin-orbit couple regime, iridate compounds have come to a focus in many experimental and theoretical studies. Especially, Sr2IrO4 has come to special interest due to 3-d parent compoun La2CuO4. Understanding the similarity and difference in the two compounds are crucial …

Pressure Induced Quantum Phase Transitions in Metallics Oxides and Pnictides
… metal oxide and a member of the pyrochlore iridate family. Resistivity measurements under pressure in moissanite anvil cells show the evolution of the ground state of the system from insulating to metallic. The quantum phase transition at Pc ∼ 6 GPa appears to be continuous. A remarkable …

Topological Phases in Perovskite Iridates with Strong Spin-Orbit Coupling
… various phases in condensed matter physics. The Iridates, which are Iridium-based compounds, have already shown rich physical phenomena and can be a perfect platform to reveal topological phases in materials with strong spin-orbit coupling. This thesis focuses on possible exotic topological …

Local Magnetism in Strongly Correlated Electron Systems with Orbital Degrees of Freedom
The central aim of my research is to explain the connection between the macroscopic behavior and the microscopic physics of strongly correlated electron systems with orbital degrees of freedom through the use of effective models. My dissertation focuses on the sub-class of these materials where …
