Topological Superconductivity in Bilayer Rashba System

Superconductivity Bordering Rashba Type Topological Transition

Strong spin orbital interaction (SOI) can induce unique quantum phenomena such as topological insulators, the Rashba effect, or p-wave superconductivity. Combining these three quantum phenomena into a single compound has important scientific implications. Here we report experimental observations of consecutive quantum phase transitions from a Rashba type topological trivial phase to topological...

d+id' chiral superconductivity in bilayer silicene.

We investigate the structure and physical properties of the undoped bilayer silicene through first-principles calculations and find the system is intrinsically metallic with sizable pocket Fermi surfaces. When realistic electron-electron interaction turns on, the system is identified as a chiral d+id' topological superconductor mediated by the strong spin fluctuation on the border of the antife...

Topological Superconductivity in Dirac Semimetals.

Dirac semimetals host bulk band-touching Dirac points and a surface Fermi loop. We develop a theory of superconducting Dirac semimetals. Establishing a relation between the Dirac points and the surface Fermi loop, we clarify how the nontrivial topology of Dirac semimetals affects their superconducting state. We note that the unique orbital texture of Dirac points and a structural phase transiti...

Topological Mechanism of Superconductivity

We outline the basic ideas of the topologigical mechanisms of su-perconductivity. A gauged model of correlated electronic system where a topological fluid is formed as a result of a strong interaction is discussed .
