Exotic Quantum Order in Low-Dimensional Systems
arXiv:cond-mat/9711233 · doi:10.1016/S0038-1098(98)00219-1
Abstract
Strongly correlated quantum systems in low dimensions often exhibit novel quantum ordering. This ordering is sometimes hidden and can be revealed only by examining new `dual' types of correlations. Such ordering leads to novel collective modes and fractional quantum numbers. Examples will be presented from quantum spin chains and the quantum Hall effect.
