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 …

Superconductivity in topological band structures is a platform for realizing Majorana bound
states and other exotic physical phenomena such as emergent supersymmetry. This …

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

Topological superconductors are predicted to harbor exotic boundary states—Majorana
zero-energy modes—whose non-Abelian braiding statistics present a new paradigm for the …

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 …

We present a detailed theoretical study of chiral topological superconductor phases in
proximity-superconducting graphene systems based on an effective model inspired by …

The search for Majorana fermions in topological superconductors is one of paramount
research targets in physics today. Using a cryogenic scanning tunneling microscopy, we …

The chiral Majorana fermion is a massless self-conjugate fermionic particle that could arise
as the quasiparticle edge state of a two-dimensonal topological state of matter. Here we …

The external controllability of topological superconductors and Majorana fermions would be
important both for fundamental and practical interests. Here we predict the electric-field …

Two-dimensional second-order topological superconductors host zero-dimensional
Majorana bound states at their boundaries. In this work, focusing on rotation-invariant …
