Electron wave video-captured by ultra-fast microscope
Electron wave running along edge of semiconductor video-captured by ultra-fast microscope
~Visualized spatial propagation of fractional quantum Hall edge~
The group of Dr. Akinori Kamiyama and Prof. Go Yusa (Department of Physics, Tohoku University) and Dr. Takaki Mano (National Institute of Material Science) have developed a scanning stroboscopic microscopy and spectroscopy which operates at extremely low temperature and high magnetic field. They succeeded in video-capturing electron waves running along an edge of a fractional quantum Hall liquid, which is one type of the topological material. This result is an important step toward unraveling exotic fractional quantum Hall liquid physics and developing a quantum universe simulator.
