The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

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 …

A wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

This article reviews odd-frequency (odd-ω) pairing with a focus on superconducting systems.
Since Berezinskii introduced the concept of odd-frequency order in 1974 it has been viewed …

Topological superconductors (TSCs), featuring fully gapped bulk and gapless surface states
as well as Majorana fermions, have potential applications in fault-tolerant topological …

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

In this article, we give a comprehensive review of recent progress in research on symmetry-
protected topological superfluids and topological crystalline superconductors, and their …

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 …

Odd-frequency superconductivity represents a truly unconventional ordered state which, in
contrast to conventional superconductivity, exhibits pair correlations which are odd in …

We point out that essentially all multiband superconductors have an odd-frequency pairing
component, as follows from a general symmetry analysis of even-and odd-frequency pairing …
