Just like insulators can present topological phases characterized by Dirac edge states,
superconductors can exhibit topological phases characterized by Majorana edge states. In …

Coupling the surface state of a topological insulator to an s-wave superconductor is
predicted to produce the long-sought Majorana quasiparticle excitations. However …

Topological insulator edges and spin-orbit-coupled quantum wires in proximity to s-wave
superconductors can be tuned through a topological quantum phase transition by a Zeeman …

Conventional topological superconductors are fully gapped in the bulk but host gapless
Majorana modes on their boundaries. We instead focus on a new class of superconductors …

Majorana bound states often occur at the end of a 1D topological superconductor. Validated
by a new bulk invariant and an intuitive edge argument, we show the emergence of one …

Heavy metals, such as Au, Ag, and Pb, often have sharp surface states that are split by
strong Rashba spin-orbit coupling. The strong spin-orbit coupling and two-dimensional …

We show that an in-plane magnetic field can drive a fully gapped p±ip topological
superconductor into a gapless phase which supports Majorana flat bands (MFBs). Unlike …

Realization of topological superconductors (TSCs) hosting Majorana fermions is a central
challenge in condensed-matter physics. One approach is to use the superconducting …

In modern theory of solids, many-electron correlations can give rise to superconductivity,
while the Berry or geometric phase is responsible for non-trivial topology. So far, these two …

The recently discovered superconductor Cu x Bi 2 Se 3 is a candidate for three-dimensional
time-reversal-invariant topological superconductors, which are predicted to have robust …
