Epitaxially grown, high quality semiconductor InSb nanowires are emerging material systems for the development of high performance nanoelectronics and quantum information processing and communication devices and for the studies of new physical phenomena in solid state systems. Here, we report on measurements of a superconductor-normal conductor-superconductor junction device fabricated from an ...

Abstract This Review examines methods to model Josephson devices such as arrays of superconducting quantum interference (SQUIDs) and rows within two-dimensional filters or SQIFs. The emphasis is on high temperature (HTS) devices, though the techniques apply for any operating temperature. use freely-available proven software first extract all self mutual inductances thin-film device, then incorp...

– We study the current-phase relation of the superconductor/normal/superconductor (SNS) junction imbedded in a superconducting loop. Considering the current conservation and free energy minimum conditions, we obtain the persistent currents of the SNS loop. At finite temperature we can explain the experimentally observed highly non-sinusoidal currents which have maxima near the zero external flu...

We consider a combined nanomechanical-supercondcuting device that allows the Cooper pair tunneling to interfere with the mechanical motion of the middle superconducting island. Coupling of mechanical oscillations of a superconducting island between two superconducting leads to the electronic tunneling generates a supercurrent that is modulated by the oscillatory motion of the island. This coupl...

The new class of phenomena described in this review is based on the interaction between spatially separated, but closely located ferromagnets and superconductors, the so-called ferromagnet–superconductor hybrids (FSH). Typical FSH are: coupled uniform and textured ferromagnetic and superconducting films, magnetic dots over a superconducting film, magnetic nanowires in a superconducting matrix, ...

We propose that a device composed of two vertically stacked monolayer graphene Josephson junctions can be used for Cooper pair splitting. The hybridization the Andreev bound states junction facilitate non-local transport in this normal-superconductor hybrid structure, which we study by calculating differential conductance. Assuming one layers is electron and other hole doped, find reflection do...

An investigation into the phonon contamination of X-ray sensitive superconducting tunnel junctions arising from the X-ray photoabsorption in various substrates has been conducted. Results are presented on the design of a superconducting tunnel junction (STJ) which substantially reduces or even eliminates phonon induced noise from the substrate. Such noise is the predominant feature in X-ray spe...

We report an experimentally observed anomalous doubly split spectrum and its split-width fluctuation in ultrastrongly coupled superconducting qubit resonator. From analysis of Rabimodel circuit model Hamiltonians, we found that the are caused by discrete charge hops due to quasiparticle tunnelings a continuous background islands flux qubit. During 70 hours measurement, width fluctuates but midd...
