Low-Noise Quantum Dots in Ultra-Shallow Ge/SiGe Heterostructures for Prototyping Hybrid Semiconducting-Superconducting Devices
M. Borovkov, Y. Schell, D. Sokolova +15
Planar germanium is currently the only semiconducting platform where high-coherence spin qubits and proximity-induced superconductivity have each been demonstrated. Recent research…
Granular aluminum induced superconductivity in germanium for hole spin-based hybrid devices
Giorgio Fabris, Paul Falthansl-Scheinecker, Devashish Shah +19
In superconductor-semiconductor hybrid structures, superconductivity and spin polarization are competing effects as magnetic fields break Cooper pairs. They can be combined using t…
Microwave radiometry of a quantum-critical, hybrid Josephson array
Kristen W. Léonard, Anton V. Bubis, Melissa Mikalsen +6
Arrays of Josephson junctions can be tuned through anomalous metallic, quantum-critical, and insulating regimes. We introduce a new experimental probe, capturing microwave radiatio…
Localization of the Helical Edge States in the Absense of External Magnetic Field
A. V. Bubis, N. N. Mikhailov, S. A. Dvoretsky +2
Theoretically, the helical edge states of two-dimensional topological insulators are protected from coherent backscattering due to nonmagnetic disorder provided electron interactio…
Thermal conductance and non-equilibrium superconductivity in a diffusive NSN wire probed by shot noise
A. V. Bubis, E. V. Shpagina, A. G. Nasibulin +1
We investigate diffusive nanowire-based structures with two normal terminals on the sides and a central superconducting island in the middle, which is either grounded or floating.…
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…
