Spin-polarized Weyl cones and gigantic anomalous Nernst effect in ferromagnetic Heusler films
Kazuki Sumida, Yuya Sakuraba, Keisuke Masuda +8
Weyl semimetals are characterized by the presence of massless band dispersion in momentum space. When a Weyl semimetal meets magnetism, large anomalous transport properties emerge…
A general route to form topologically-protected surface and bulk Dirac fermions along high-symmetry lines
O. J. Clark, F. Mazzola, I. Marković +11
The band inversions that generate the topologically non-trivial band gaps of topological insulators and the isolated Dirac touching points of three-dimensional Dirac semimetals gen…
Prolonged photo-carriers generated in a massive-and-anisotropic Dirac material
Munisa Nurmamat, Yukiaki Ishida, Ryohei Yori +8
Transient electron-hole pairs generated in semiconductors can exhibit unconventional excitonic condensation. Anisotropy in the carrier mass is considered as the key to elongate the…
Large-gap magnetic topological heterostructure formed by subsurface incorporation of a ferromagnetic layer
Toru Hirahara, Sergey V. Eremeev, Tetsuroh Shirasawa +17
Inducing magnetism into topological insulators is intriguing for utilizing exotic phenomena such as the quantum anomalous Hall effect (QAHE) for technological applications. While m…
Direct evidence of hidden local spin polarization in a centrosymmetric superconductor LaOFBiS
Shi-Long Wu, Kazuki Sumida, Koji Miyamoto +9
Conventional Rashba spin polarization is caused by the combination of strong spin-orbit interaction (SOI) and spatial inversion asymmetry. However, Rashba- and Dresselhaus-type spi…
Ultrafast electron dynamics at the Dirac node of the topological insulator SbTe
Siyuan Zhu, Yukiaki Ishida, Kenta Kuroda +8
Topological insulators (TIs) are a new quantum state of matter. Their surfaces and interfaces act as a topological boundary to generate massless Dirac fermions with spin-helical te…
