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

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

Fermions—elementary particles such as electrons—are classified as Dirac, Majorana or
Weyl. Majorana and Weyl fermions had not been observed experimentally until the recent …

Based on the ab initio calculations, we show that MoTe 2, in its low-temperature
orthorhombic structure characterized by an x-ray diffraction study at 100 K, realizes 4 type-II …

The recently discovered type-II Weyl points appear at the boundary between electron and
hole pockets. Type-II Weyl semimetals that host such points are predicted to exhibit a new …

We study the stability of gap-closing (Weyl or Dirac) points in the three-dimensional Brillouin
zone of semimetals using Clifford algebras and their representation theory. We show that a …

Topological insulators, in contrast to ordinary semiconductors, accompany protected metallic
surfaces described by Dirac-type fermions. Here, we theoretically show that another …

We investigate the topological aspect of the spin-triplet f-wave superconductor UPt3 through
microscopic calculations of edge-and vortex-bound states based on the quasiclassical …

The electronic and topological properties of materials are derived from the interplay between
crystalline symmetry and dimensionality. Simultaneously introducing “forbidden” symmetries …

Owing to the richness of symmetry and well-established knowledge of bulk superfluidity, the
superfluid 3 He has offered a prototypical system to study intertwining of topology and …
