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…
