Scientists Directly Observe Spin Quadrupoles for the First Time
South Korean researchers have made a groundbreaking discovery by directly observing spin quadrupoles in a spin-nematic phase using advanced x-ray and optical techniques. This achievement in studying Sr2IrO4 opens new possibilities in quantum computing and high-temperature superconductivity research.The “spin-nematic phase,” a magnetic analog of liquid crystal, has been observed for the first time in a quantum spin system.Liquid crystal represents a unique state of matter, combining characteristics of both liquids and…
