Spin liquids are a state of matter found in certain magnetic materials where the magnetic moments, or spins, do not settle into a fixed arrangement, even at very low temperatures. Instead, these spins remain in a fluctuating, disordered state, leading to unique properties such as long-range entanglement and the potential for quantum computing applications. This phenomenon occurs in materials like frustrated magnets, where competing interactions prevent the spins from aligning. Researchers study spin liquids to understand their behavior and explore their implications for quantum physics and condensed matter physics, as they challenge traditional concepts of magnetism and order.
