Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

In non-centrosymmetric superconductors, where the crystal structure lacks a centre of
inversion, parity is no longer a good quantum number and an electronic antisymmetric spin …

The diode effect is fundamental to electronic devices and is widely used in rectifiers and ac–
dc converters. At low temperatures, however, conventional semiconductor diodes possess a …

During the past 15 years a new field has emerged, which combines superconductivity and
spintronics, with the goal to pave a way for new types of devices for applications combining …

This review elaborates pedagogically on the fundamental concept, basic theory, expected
properties, and materials realizations of topological superconductors. The relation between …

There has been increasing interest in phenomena emerging from relativistic electrons in a
solid, which have a potential impact on spintronics and magnetoelectrics. One example is …

We systematically study topological phases of insulators and superconductors (or
superfluids) in three spatial dimensions. We find that there exist three-dimensional (3D) …

'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …

Since the 1950s, Heisenberg and others have addressed the problem of how to explain the
appearance of countable particles in continuous fields. Stable localized field configurations …

The proximity effect at superconductor-ferromagnet interfaces produces damped oscillatory
behavior of the Cooper pair wave function within the ferromagnetic medium. This is …
