Quantum Critical Magnetic Excitations in Spin-1/2 and Spin-1 Chain Systems

The study of CoNb_{2}O_{6} sits at the confluence of simplicity and complexity: on one hand, the model for Ising chains—the building blocks of CoNb_{2}O_{6}—in a transverse field can be exactly solved and, thus, serves as an archetype of quantum criticality; on the other hand, the weak but nonzero i...
