A non-magnetic mechanism of backscattering in helical edge states
I. V. Krainov, R. A. Niyazov, D. N. Aristov +1
We study interaction-induced backscattering mechanism for helical edge states of a two-dimensional topological insulator which is tunnel-coupled to a puddle located near the edge c…

Shot noise in Aharonov-Bohm interferometers: Comparison of helical and conventional setups
R. A. Niyazov, I. V. Krainov, D. N. Aristov +1
We study tunneling transport through quantum Aharonov-Bohm (AB) interferometers and demonstrate that interference effects strongly modify shot noise of the current. We discuss in d…

Thermoelectric and viscous contributions to the hydrodynamic ratchet effect
S. O. Potashin, L. E. Golub, V. Yu. Kachorovskii
We study thermoelectric and viscous contributions to the ratchet effect, i.e. radiation-induced generation of the direct electric current, in asymmetric dual-grating…
