Electronic properties and structures in multi-orbital strongly correlated system

我们研究了多轨道系统的电子结构，这些系统表现出反常的电子性质，如金属-绝缘体转变，超导电性，量子临界性，磁有序，以及自旋-轨道相互作用引起的自旋分裂。通过使用包括同步加速器和激光在内的各种光源的角分辨光电子能谱，阐明了异常和新的物理性质的机制，从而使得高分辨率、偏振相关和时间分辨的测量成为可能。

We investigated the electronic structure of multi-orbital systems, which show anomalous electronic properties such as metal-insulator transition, superconductivity, quantum criticality, magnetic order, and spin-splitting induced by spin-orbit interaction. The mechanisms of anomalous and novel physical properties were clarified by means of angular-resolved photoemission spectroscopy using a variety of light sources including synchrotrons and lasers, thus enabling the high-resolution, polarization-dependet, and time-resolved measurements.
