Abstract Majorana fermions are spin-1/2 neutral particles that are their own antiparticles and
were initially predicted by Ettore Majorana in particle physics but their observation still …

Superconductivity is a phenomenon where the macroscopic quantum coherence appears
due to the pairing of electrons. This offers a fascinating arena to study the physics of …

Finding a means to generate, control and use spin-polarized currents represents an
important challenge for spin-based electronics,,, or 'spintronics'. Spin currents and the …

Recent experiments on mesoscopic normal metal/superconductor heterostructures resolve
properties on length scales and at low temperatures such that the temperature is below the …

Fabrication of structures at the atomic scale is now possible using state-of-the-art techniques
for manipulating individual atoms, and it may become possible to design electrical circuits …

The purpose of this review is to provide a comprehensive pedagogical introduction into
Keldysh technique for interacting out-of-equilibrium fermionic and bosonic systems. The …

Superconducting properties of metallic nanowires can be entirely different from those of bulk
superconductors because of the dominating role played by thermal and quantum …

A ferromagnetic insulator (FI) attached to a conventional superconductor (S) changes
drastically the properties of the latter. Specifically, the exchange field at the FI/S interface …

An overview of a theory of electromagnetic response of superconductors in strong radio-
frequency (RF) electromagnetic fields is given with the emphasis on applications to …

We report measurements on ropes of single-walled carbon nanotubes (SWNT) in low-
resistance contact to nonsuperconducting (normal) metallic pads, at low voltage and at …
