Observation of the possible chiral edge mode in Bi1-xSbx
M. Sasaki, A. Ohnishi, Nabyendu Das +2
After the classification of topological states of matter has been clarified for non-interacting electron systems, the theoretical connection between gapless boundary modes and nont…

Two-parameter scaling theory of the longitudinal magnetoconductivity in a Weyl metal phase: Chiral anomaly, weak disorder, and finite temperature
Kyoung-Min Kim, Dongwoo Shin, M. Sasaki +3
It is at the heart of modern condensed matter physics to investigate the role of a topological structure in anomalous transport phenomena. In particular, chiral anomaly turns out t…

Interplay between disorder and inversion symmetry: Extreme enhancement of the mobility near the Weyl point in BiTeI
M. Sasaki, Kyoung-Min Kim, A. Ohnishi +5
We show experimental and theoretical evidence that BiTeI hosts a novel disordered metallic state named diffusive helical Fermi liquid (DHFL), characterized by a pair of concentric…
