In electronic band structure of solid-state material, two band-touching points with linear dispersion appear in pairs in the momentum space. When they annihilate each other, the system undergoes a quantum phase transition from a three-dimensional ...

The three-dimensional Anderson model is a well-studied model of disordered electron systems that shows the delocalization-localization transition. As in our previous papers on two- and three-dimensional (2D, 3D) quantum phase transitions [J. Phys....

Topological properties are sometimes emergent or enforced by the breaking of translational invariance. Here, in this chapter we discuss dimensional crossover of topological properties in thin films of topological insulators (TI) and Weyl semi- met...
文部科学省の現代GP,グローバル社会における系統的科学英語教育の支援を受け,カリキュラム委員長として30科目以上にわたる表記の科目群を整えた。また実際に物理系の科目を,パワーポイント,WEBサイト,DVD(The mechanical universe and beyond..)を用い,リスニング,ライティング,リーディングを教えた。\nまた本プログラムは30科目以上の講義からなるが,そのカリキュラム委員長を務めた。さらに各種の電子教材を作成した。
