Quantum Phases in Chromium Material Suggest Spin-Triplet Superconductivity

Researchers identified three distinct quantum phases in a chromium-based material, K2Cr3As3, below 6.2 K, indicating potential spin-triplet superconductivity. This finding, published in Nature Physics, advances understanding of superconductivity, though the mechanism for Majorana excitations in one phase is still unknown. The discovery contributes to fundamental physics research.
