This review elaborates pedagogically on the fundamental concept, basic theory, expected properties, and materials realizations of topological superconductors. The relation between topological superconductivity and Majorana fermions are explained, and the difference between dispersive Majorana fermions and a localized Majorana zero mode is emphasized. A variety of routes to topological superconductivity are explained with an emphasis on the roles of spin-orbit coupling. Present experimental… Expand

Prediction of Phonon-Mediated Superconductivity with High Critical Temperature in the Two-Dimensional Topological Semimetal W2N3.
TLDR
This work predicts a remarkably high superconducting critical temperature of 21 K in the easily exfoliable, topologically nontrivial 2D semimetal W2N3 and finds large changes in the electron-phonon interactions that make this material a unique platform to study different coupling regimes and test the limits of current theories of superconductivity.

Topological phases in nodeless tetragonal superconductors.
TLDR
It is demonstrated that 2D tetragonal superconductors show surprising topological features: non-trivial high Chern numbers, massive edge states, and zero-energy modes out of high symmetry points, even though the edge states remain topologically protected. Expand

TLDR
The zero bias conductance peak (ZBCP), a typical signature of the Majorana-bound state, has been observed at the ends of nanowires or vortex cores by tunneling measurements, but there is still a lot of debate over whether the ZBCP in these measurements is truly from theMajorana- bound state. Expand
