1D spin systems

A 1D spin system consists of a chain of particles, each with a property called "spin," which is akin to a tiny magnetic moment. These spins can interact with their neighbors, aligning or opposing each other, leading to different magnetic behaviors. Such systems are studied to understand fundamental physics, phase transitions, and quantum effects in low dimensions. Despite their simplicity, 1D spin models reveal rich phenomena like quantum entanglement and criticality, providing insights relevant to advanced materials and quantum computing.
