The focusing effect of electron flow and negative refraction in three dimensional topological insulators
Wang Kai-Tong, Xing Yanxia, Cheung King Tai +3
We studied the focusing effect of electron flow induced by a single p-n junction (PNJ) in three-dimensional topological insulator. It is found that the electrons flowing from the n…

Wess-Zumino-Berry phase interference in spin tunneling at excited levels with a magnetic field
Pan Hui, Rong Lu, Jia-Lin Zhu +1
Macroscopic quantum coherence and spin-phase interference are studied between excited levels in single-domain ferromagnetic particles in a magnetic field along the hard anisotropy…
