Quantum oscillations of helical edge states of periodically deformed 2D topological insulator in magnetic field
A. V. Tsvetkova, P. D. Grigoriev, Ya. I. Rodionov
We study edge-state transport in a two-dimensional topological insulator with a periodically deformed edge subjected to a uniform magnetic field. Zeeman coupling breaks time-revers…
Nesting-driven ferromagnetism of itinerant electrons
Ya. I. Rodionov, A. V. Rozhkov, M. E. S. Beck +3
We theoretically investigate a model with electrons and holes whose Fermi surfaces are perfectly nested. The fermions are assumed to be interacting, both with each other and with t…
Density of electronic states in density-wave compounds with imperfect nesting
A. V. Tsvetkova, Ya. I. Rodionov, P. D. Grigoriev
We study the effects of imperfect nesting in a simple 2D tight-binding model on the electronic properties in the density-wave (DW) state. The discussed model reflects the main feat…
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…
Adiabatic dechiralisation and thermodynamics of Weyl semimetals
S. V. Syzranov, Ya. I. Rodionov, B. Skinner
We study thermodynamic manifestations of the chiral anomaly in disordered Weyl semimetals. We focus, in particular, on the effect which we call 'adiabatic dechiralization,' the phe…
Conductivity of a Weyl semimetal with donor and acceptor impurities
Ya. I. Rodionov, S. V. Syzranov
We study transport in a Weyl semimetal with donor and acceptor impurities. At sufficiently high temperatures transport is dominated by electron-electron interactions, while the low…
