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…
Effective Hamiltonian of topologically protected qubit in a helical crystal
R. A. Niyazov, D. N. Aristov, V. Yu. Kachorovskii
We study a superlattice formed by tunnel-coupled identical antidots periodically situated in a two-dimensional topological insulator placed in a magnetic field. The superlattice sp…
Spin and charge transport through helical Aharonov-Bohm interferometer with strong magnetic impurity
R. A. Niyazov, D. N. Aristov, V. Yu. Kachorovskii
We discuss transport through an interferometer formed by helical edge states of the quantum spin Hall insulator. Focusing on effects induced by a strong magnetic impurity placed in…
