Surprises in Quantum Magnetism: Tetris, Entanglement, and Spin Liquids

Advances in understanding quantum states in spin networks are closely tied to quantum information. Entanglement and its consequences provide ways to not only generate new physical phenomena but also to realize topological quantum information processing. These developments pose new challenges to experiment and understanding of quantum coherence and its relation to temperature.

I explore this by showing recent work on application of entanglement witnesses to neutron experiments and other work on unexpected thermal effects on highly quantum states.
