This review provides a theoretical basis for understanding the current-phase relation (CΦR)
for the stationary (dc) Josephson effect in various types of superconducting junctions. The …

This article is an overview of recent experimental and theoretical work on transport in phase-
coherent hybrid nanostructures, with particular emphasis on dc electrical conduction. A …

We study junctions between superconductors mediated by the edge states of a quantum-
spin-Hall insulator. We show that such junctions exhibit a fractional Josephson effect, in …

Recent studies on high-T c superconductors have aroused new interest in tunnelling effects
in unconventional superconductors. Unlike in conventional s-wave superconductors, the d …

We model theoretically a two-dimensional electron gas (2DEG) covered by a
superconductor and demonstrate that topological superconducting channels are formed …

A microscopic theory of the transport properties of quantum point contacts giving a unified
description of the normal conductor-superconductor (NS) and superconductor …

We propose and analyze a spin-entangler for electrons based on an s-wave superconductor
coupled to two quantum dots, each of which is coupled to normal Fermi leads. We show that …

Measurement of multiple Andreev Reflection (MAR) in a Josephson junction made from an
InAs quantum well heterostructure with epitaxial aluminum is used to quantify a highly …

A weakly biased normal-metal-superconductor junction is considered as a potential device
injecting entangled pairs of quasi-particles into a normal-metal lead. The two-particle states …

The controlled growth of nanowires (NWs) with dimensions comparable to the Fermi
wavelengths of the charge carriers allows fundamental investigations of quantum …
