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

Emergent electronic phenomena in iron-based superconductors have been at the forefront
of condensed matter physics for more than a decade. Much has been learned about the …

Topological materials and unconventional iron-based superconductors are both important
areas of study but, to date, relatively little overlap has been identified between these two …

We identify three-dimensional higher-order superconductors characterized by the
coexistence of one-dimensional Majorana hinge states and gapless surface states. We …

Investigations of perovskite oxides triggered by the discovery of high-temperature and
unconventional superconductors have had crucial roles in stimulating and guiding the …

Characterized by bulk Dirac or Weyl cones and surface Fermi-arc states, topological
semimetals have sparked enormous research interest in recent years. The nanostructures …

The superconductor PdTe 2 was recently classified as a type-II Dirac semimetal, and
advocated to be an improved platform for topological superconductivity. Here, we report …

The interplay of nontrivial topology and superconductivity in condensed matter physics gives
rise to exotic phenomena. However, materials are extremely rare where it is possible to …

We introduce higher-order topological Dirac superconductor (HOTDSC) as a gapless
topological phase of matter in three dimensions, which extends the notion of Dirac phase to …

The combination of superconductivity and surface states in Dirac semimetal can produce a 4
π-periodic supercurrent in a Josephson junction configuration, which can be revealed by the …
