Semiclassical scattering by edge imperfections in topological insulators under magnetic field
A. S. Dotdaev, Ya. I. Rodionov, A. V. Rozhkov +1
We study the scattering of edge states of 2D topological insulator (TI) in the uniform external magnetic field due to edge imperfections, common in realistic 2D TI samples. The ext…
Effects of anisotropy on the high field magnetoresistance of Weyl semimetals
A. S. Dotdaev, Ya. I. Rodionov, K. I. Kugel +1
We study the effects of anisotropy on the magnetoresistance of Weyl semimetals (WSMs) in the ultraquantum regime. We utilize the fact that many Weyl semimetals are approximately ax…
Instantons in the out-of-equilibrium Coulomb blockade
A. S. Dotdaev, Ya. I. Rodionov, K. S. Tikhonov
Physical properties of single-electron devices in the week Coulomb blockade regime are significantly dependent on non-perturbative effects. They arise as instanton solutions of equ…
