Charge-neutral nonlocal response in superconductor-InAs nanowire hybrid devices
A. O. Denisov, A. V. Bubis, S. U. Piatrusha +8
Nonlocal quasiparticle transport in normal-superconductor-normal (NSN) hybrid structures probes sub-gap states in the proximity region and is especially attractive in the context o…
Spatial and energy resolution of electronic states by shot noise
E. S. Tikhonov, A. O. Denisov, S. U. Piatrusha +5
Shot noise measurements are widely used for the characterization of nonequilibrium configurations in electronic conductors. The recently introduced quantum tomography approach was…
Universal bottleneck for thermal relaxation in disordered metallic films
E. M. Baeva, N. A. Titova, A. I. Kardakova +2
We study the heat relaxation in current biased metallic films in the regime of strong electron-phonon coupling. A thermal gradient in the direction normal to the film is predicted,…
Topological protection brought to light by the time-reversal symmetry breaking
S. U. Piatrusha, E. S. Tikhonov, Z. D. Kvon +3
Recent topological band theory distinguishes electronic band insulators with respect to various symmetries and topological invariants, most commonly, the time reversal symmetry and…
Strategy for accurate thermal biasing at the nanoscale
Artem Denisov, Evgeny Tikhonov, Stanislau Piatrusha +6
We analyze the benefits and shortcomings of a thermal control in nanoscale electronic conductors by means of the contact heating scheme. Ideally, this straightforward approach allo…
Noise insights into electronic transport
S. U. Piatrusha, L. V. Ginzburg, E. S. Tikhonov +6
Typical experimental measurement is set up as a study of the system's response to a stationary external excitation. This approach considers any random fluctuation of the signal as…
