Investigation of novel quantum states in actinide-based compounds with unstable valence

本项目的主要目的是建立锕系元素物理研究基地研究所。为此，我们在日本东北大学材料研究所α射线发射体实验室建造了一个四弧炉，用于铀基材料的单晶生长，并建立了商用设备，用于测量生长的单晶的物理性质。此外，我们还开辟了一条研究包括准晶体在内的4f和5f电子系统中与价态不稳定性相关的新现象的新途径。

The main purpose of this project is to establish a base institute for the study on the actinide physics. For this purpose, we constructed a tetra-arc furnace at Laboratory of alpha-Ray Emitters, Insitute for Materials Research, Tohoku University, for the single crystal growth of uranium-based materials, and set up commercial equipmentsfor the measurements of the physical properties of grown single crystals as well. Furthermore, we opened a new avenue of research on novel phenomena that will be related to valence instability in both 4f and 5f electron systems including quasicrystals.
