Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

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

While the topological classification of insulators, semimetals, and superconductors in terms
of nonspatial symmetries is well understood, less is known about topological states …

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 …

Starting from a microscopic itinerant model, we derive and analyze the effective low-energy
model for collective magnetic excitations in the iron pnictides. We show that the stripe …

We introduce the concept of three-dimensional Dirac (Weyl) superconductors (SC), which
have protected bulk fourfold (twofold) nodal points and surface Majorana arcs at zero …

Topological media are systems whose properties are protected by topology and thus are
robust to deformations of the system. In topological insulators and superconductors the bulk …

We systematically study gapless topological phases of (semi-) metals and nodal
superconductors described by Bloch and Bogoliubov–de Gennes Hamiltonians. Using K …

Topological superconductors have become a subject of intense research due to their
potential use for technical applications in device fabrication and quantum information …

In all known fermionic superfluids, Cooper pairs are composed of spin-1/2 quasi-particles
that pair to form either spin-singlet or spin-triplet bound states. The “spin” of a Bloch electron …
