Exotic superconducting states could exist in a wider range of materials than previously thought, according to a theoretical ...

A shiny gray crystal called platinum-bismuth-two hides an electronic world unlike anything scientists have seen before.

Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century. While conventional superconductors are well understood, a new class of ...

PtBi2 looks like an ordinary grey crystal, but a new study shows its electrons move in unusual ways not seen in other materials. In 2024 (Nature, "Evidence of superconducting Fermi arcs"), the ...

A multi-institutional team of scientists has developed a new superconductor material that could potentially be used in quantum computing and be a candidate 'topological superconductor.' A ...

While superconductors are known to induce weak superconducting behavior in nearby materials, the iron's induced behavior was ...

Topological superconductors are materials that, beyond simply exhibiting superconductivity, possess a topological order. This order refers to the global properties of the material's wavefunctions that ...

Topological superconductors are predicted to host exotic Majorana states that obey non-Abelian statistics and can be used to implement a topological quantum computer. Most of the proposed topological ...

As part of the Quantum Science Center headquartered at ORNL, Robert Moore probes the interface between a topological insulator and a superconductor with spin- and angle-resolved photoemission ...
