Observation of Josephson harmonics in tunnel junctions. [PDF]

Nat Phys, 2023
Approaches to developing large-scale superconducting quantum processors must cope with the numerous microscopic degrees of freedom that are ubiquitous in solid-state devices.

Nonequilibrium effects in tunnel Josephson junctions [PDF]

Physical Review B, 2005
We study nonequilibrium effects in current transport through voltage biased tunnel junction with long diffusive superconducting leads at low applied voltage, $eV \ll 2\Delta$, and finite temperatures.

Confocal Annular Josephson Tunnel Junctions [PDF]

Journal of Low Temperature Physics, 2016
The physics of Josephson tunnel junctions drastically depends on their geometrical configurations and here we show that also tiny geometrical details play a determinant role.

Properties of tunnel Josephson junctions with a ferromagnetic interlayer [PDF]

, 2008
We investigate superconductor/insulator/ferromagnet/superconductor (SIFS) tunnel Josephson junctions in the dirty limit, using the quasiclassical theory.

Phase Control of Bipolar Thermoelectricity in Josephson Tunnel Junctions [PDF]

Physical Review Applied, 2022
Not so long ago, thermoelectricity in superconductors was believed to be possible only by breaking explicitly the particle-hole symmetry. Recently, it has been theoretically predicted that a superconducting tunnel junction can develop bipolar ...

Electrodynamics of Highly Spin-Polarized Tunnel Josephson Junctions [PDF]

, 2020
The continuous development of superconducting electronics is encouraging several studies on hybrid Josephson junctions (JJs) based on superconductor/ferromagnet/superconductor (SFS) heterostructures, as either spintronic devices or switchable elements in

Probing defect densities at the edges and inside Josephson junctions of superconducting qubits [PDF]

npj Quantum Information, 2021
Tunneling defects in disordered materials form spurious two-level systems which are a major source of decoherence for micro-fabricated quantum devices.

Current-voltage characteristics of tunnel Josephson junctions with a ferromagnetic interlayer [PDF]

, 2011
We present a quantitative study of the current-voltage characteristics (CVC) of diffusive superconductor/ insulator/ ferromagnet/ superconductor (SIFS) tunnel Josephson junctions. In order to obtain the CVC we calculate the density of states (DOS) in the

All-MgB2 Josephson tunnel junctions [PDF]

Applied Physics Letters, 2005
Sandwich-type all-MgB2 Josephson tunnel junctions (MgB2∕AlOx∕MgB2) have been fabricated with as-grown MgB2 films formed by molecular-beam epitaxy. The junctions exhibit substantial superconducting current (IcRN product ∼0.8mV at 4.2 K), a well-defined superconducting gap (Δ=2.2–2.3mV), and clear Fraunhofer patterns. The superconducting gap voltage of Δ
