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…
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…
Tunable helical crystals
R. A. Niyazov, D. N. Aristov, V. Yu. Kachorovskii
We consider a superlattice formed by tunnel-connected identical holes, periodically placed in a two-dimensional topological insulator. We study tunneling transport through helical…
Disorder-driven transition to tubular phase in anisotropic two-dimensional materials
M. V. Parfenov, V. Yu. Kachorovskii, I. S. Burmistrov
We develop a theory of anomalous elasticity in disordered two-dimensional flexible materials with orthorhombic crystal symmetry. Similar to the clean case, we predict existence of…
