Topological blocking at the Bi(111) surface due to surface relaxation
Kazuki Koie, Rikako Yaguchi, Yuki Fuseya
The topological characteristics of Bi and its alloys with Sb have fueled intense debate since the prediction of three-dimensional topological insulators. However, a definitive reso…
High-field immiscibility of electrons belonging to adjacent twinned bismuth crystals
Yuhao Ye, Akiyoshi Yamada, Yuto Kinoshita +16
Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twi…
Effects of strain-tunable valleys on charge transport in bismuth
Suguru Hosoi, Fumu Tachibana, Mai Sakaguchi +6
The manipulation of the valley degree of freedom can boost the technological development of novel functional devices based on valleytronics. The current mainstream platform for val…
Quantum--classical correspondence and dissipative to dissipationless crossover in magnetotransport phenomena
Akiyoshi Yamada, Yuki Fuseya
The three-dimensional magneto-conductivity tensor was derived in a gauge invariant form based on the Kubo formula considering the quantum effect under a magnetic field, such as the…
Negative transverse magnetoresistance due to negative off-diagonal mass in linear dispersion materials
Yudai Awashima, Yuki Fuseya
This study calculated the magnetoresistance (MR) in the Dirac electron system, Dressellhaus-Kip-Kittel (DKK) model, and nodal-line semimetals based on the semiclassical Boltzmann t…
A field-induced reentrant insulator state of a gap-closed topological insulator (Bi_{1-x}Sb_x) in quantum-limit states
Y. Kinoshita, T. Fujita, R. Kurihara +4
In the extreme quantum limit states under high magnetic fields, enhanced electronic correlation effects can stabilize anomalous quantum states. Using band-tuning with a magnetic fi…
