Topological Lifshitz transitions involve many types of topological structures in momentum
and frequency–momentum spaces, such as Fermi surfaces, Dirac lines, Dirac and Weyl …

Topological electronic flattened bands near or at the Fermi level are a promising route
towards unconventional superconductivity and correlated insulating states. However, the …

Weyl points in three spatial dimensions are characterized by a Z-valued charge—the Chern
number—which makes them stable against a wide range of perturbations. A set of Weyl …

We present a comprehensive theory for Bogoliubov Fermi surfaces in inversion-symmetric
superconductors which break time-reversal symmetry. A requirement for such a gap …

We study the topological properties of superconductors with paired j= 3 2 quasiparticles.
Higher spin Fermi surfaces can arise, for instance, in strongly spin-orbit coupled band …

We investigate topological Cooper pairing, including gapless Weyl and fully gapped class
DIII superconductivity, in a three-dimensional doped Luttinger semimetal. The latter …

Motivated by the experimental detection of superconductivity in the low-carrier density half-
Heusler compound YPtBi, we study the pairing instabilities of three-dimensional strongly …

Determination of the symmetry property of superconducting gaps has been a central issue in
studies to understand the mechanisms of unconventional superconductivity. Although it is …

In superconductors, electrons with spin s= 1/2 form Cooper pairs whose spin structure is
usually singlet (S= 0) or triplet (S= 1). When the electronic structure near the Fermi level is …

The systematic diagnosis of band topology enabled by the method of “symmetry indicators”
underlies the recent advances in the search for new materials realizing topological …
