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 …

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 …

Nonreciprocal responses of noncentrosymmetric quantum materials attracted recent
intensive interests, which is essential for the rectification function in diodes. A recent …

The Josephson effect describes the generic appearance of a supercurrent in a weak link
between two superconductors. Its exact physical nature deeply influences the properties of …

The Josephson effect describes supercurrent flowing through a junction connecting two
superconducting leads by a thin barrier. This current is driven by a superconducting phase …

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 …

Theory of dispersionless Andreev bound states on surfaces of time-reversal-invariant
unconventional superconductors is presented. The generalized criterion for the …

We review theoretical and experimental highlights in transport in two-dimensional
topological materials over the last five years. Topological materials comprise topological …

For certain orientations of Josephson junctions between two px-wave or two d-wave
superconductors, the subgap Andreev bound states produce a 4π-periodic relation between …

The Josephson rectification effect, where the resistance is finite in one direction while zero in
the other, has been recently realized experimentally. The resulting Josephson diode has …
