Wiedemann-Franz behavior at the Weyl points in compressively strained HgTe
Abu Alex Aravindnath, Yi-Ju Ho, Fabian Schmitt +6
Weyl semimetals, with their unique electronic band structure, have drawn significant interest for their potential to explore quantum anomalies in condensed matter systems. In this…
Phase-dependent supercurrent and microwave dissipation of HgTe quantum well Josephson junctions
Wei Liu, Stanislau U. Piatrusha, Lena Fürst +4
We measured the microwave response of a HgTe quantum well Josephson junction embedded into an RF SQUID loop which is inductively coupled to a superconducting resonator. The side-co…
Period-doubling in the phase dynamics of a shunted HgTe quantum well Josephson junction
Wei Liu, Stanislau U. Piatrusha, Xianhu Liang +7
The fractional AC Josephson effect is a discerning property of topological superconductivity in hybrid Josephson junctions. Recent experimental observations of missing odd Shapiro…
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…
Heat-mode excitation in a proximity superconductor
A. O. Denisov, A. V. Bubis, S. U. Piatrusha +8
Mesoscopic superconductivity deals with various quasiparticle excitation modes, only one of them -- the charge-mode -- being directly accessible for conductance measurements due to…
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…
Measuring electron energy distribution by current fluctuations
S. U. Piatrusha, V. S. Khrapai
A recent concept of local noise sensor is extended to measure the energy resolved electronic energy distribution at a given location inside a non-equilibrium norma…
Edge States in Lateral p-n Junctions in Inverted Band HgTe Quantum Wells
S. U. Piatrusha, V. S. Khrapai, Z. D. Kvon +3
We investigate lateral p-n junctions, electrostatically defined in 14 nm-wide HgTe-based quantum wells (QWs) with inverted band structure. The p-n junctions resistances are close t…
