Quantum spin chains
A spin chain is a line of interacting quantum spins, often exactly solvable on paper, yet how spin and heat move along it at finite temperature has turned out unexpected. Some chains also have phases whose existence is still disputed.
Why it matters
One-dimensional magnets allow exact comparison between theory, numerics, materials and quantum simulators.
