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…
Finite-frequency conductivity of nonlinear Luttinger liquid in smooth random potential
A. A. Dontsov, D. N. Aristov, A. P. Dmitriev
We analyze the uniform conductivity of a one-dimensional degenerate fermion system placed in a random disorder potential so smooth that backward scattering can be neglected. We use…
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…
Coherent spin transport through helical edge states of topological insulator
R. A. Niyazov, D. N. Aristov, V. Yu. Kachorovskii
We study coherent spin transport through helical edge states of topological insulator tunnel-coupled to metallic leads. We demonstrate that unpolarized incoming electron beam acqui…
Y-junction of Luttinger-liquid wires out of equilibrium
D. N. Aristov, I. V. Gornyi, D. G. Polyakov +1
We calculate the conductances of a three-way junction of spinless Luttinger-liquid wires as functions of bias voltages applied to three independent Fermi-liquid reservoirs. In part…
Ambiguity in renormalization of X-junction between Luttinger liquid wires
D. N. Aristov, R. A. Niyazov
We study four-lead junction of semi-infinite wires by using fermionic representation in the scattering state formalism. The model of spinless fermions with short-range Luttinger li…
