News: Recently, A team of scientists has used computational techniques to design a novel 2D composite quantum material that exhibits an exotic quantum property called Rashba splitting.

What is Composite Quantum Material?
• A composite quantum material is a material that combines two different quantum properties in one substance. Quantum properties are the physical characteristics of matter that are governed by the laws of quantum mechanics, such as superconductivity, magnetism, topological order, and so on.
• For example, a 2-D carbide structure named Mo2COX displays both the Rashba effect and nonlinear anomalous Hall effect, offering the potential for advanced spintronic devices.

What is Rashba Splitting?
• Rashba splitting is a quantum phenomenon in materials where spin-up and spin-down electrons separate due to interactions with an electric field.
• For instance, in a 2-D carbide material, Rashba splitting causes momentum-dependent separation of electron spin bands, enabling novel spintronic device applications.
• Quantum materials possess unique physical properties that stem from quantum effects like coherence and entanglement. These properties have the potential to revolutionize quantum technology applications, including quantum computing, communication, sensors, and memory devices.
