Hybrid interfaces where organic molecules are adsorbed on metallic substrates are very interesting to understand the fundamental interactions that might modify the chemical-physical properties of molecules or substrate. Here, we explore the adsorptio

Publikováno v: Science Advances

Topological superconductors are predicted to harbor exotic boundary states - Majorana zero-energy modes - whose non-Abelian braiding statistics present a new paradigm for the realization of topological quantum computing. Using low-temperature scannin

We demonstrate the artificial construction of magnetic atom chains on a conventional superconductor as a Majorana platform.
Realizing Majorana bound states (MBS) in condensed matter systems is a key challenge on the way toward topological quantu
