Suppression of ballistic helical transport by isotropic dynamical magnetic impurities
Oleg M. Yevtushenko, Vladimir I. Yudson
Dynamical magnetic impurities (MI) are considered as a possible origin for suppression of the ballistic helical transport on edges of 2D topological insulators. The MIs provide a s…
Protection of Edge transport in Quantum Spin Hall samples: Spin-Symmetry Based General Approach and Examples
Oleg M. Yevtushenko, Vladimir I. Yudson
Understanding possible mechanisms, which can lead to suppression of helical edge transport in Quantum Spin Hall (QSH) systems, attracted huge attention right after the first experi…
Transport in helical Luttinger Liquid with Kondo impurities
O. M. Yevtushenko, A. Wugalter, V. I. Yudson +1
Ballistic transport of helical edge modes in two-dimensional topological insulators is protected by time-reversal symmetry. Recently it was pointed out [1] that coupling of non-int…
Localization at the Edge of 2D Topological Insulator by Kondo Impurities with Random Anisotropies
B. L. Altshuler, I. L. Aleiner, V. I. Yudson
We consider chiral electrons moving along the 1D helical edge of a 2D topological insulator and interacting with a disordered chain of Kondo impurities. Assuming the electron-spin…
Delocalization by Disorder in Layered Systems
Dmitrii L. Maslov, Vladimir I. Yudson, Andres M. Somoza +1
Motivated by anomalously large conductivity anisotropy in layered materials, we propose a simple model of randomly spaced potential barriers (mimicking stacking faults) with isotro…
Universality in scattering by large-scale potential fluctuations in two-dimensional conductors
Vladimir I. Yudson, Dmitrii L. Maslov
We study electron propagation through a random array of rare, opaque and large (compared the de Broglie wavelength of electrons) scatterers. It is shown that for any convex scatter…
Electron kinetics in isolated mesoscopic rings driven out of equilibrium
V. I. Yudson, V. E. Kravtsov
Kinetic theory of nonlinear current response to an external field is developed for mesoscopic normal metal rings threaded by a magnetic flux. General expressions for direct current…
