| Frustration in Low Dimensional Systems
|
| In this lecture I will introduce the notion of geometric frustration and discuss its multiple consequences for low dimensional quantum magnets. We will analyze the role of frustration in different models. In some cases, the theoretical predictions will be contrasted with experimental results on magnetic insulators that are well described by the corresponding model Hamiltonian. We will also construct models based on theoretical grounds to demonstrate the possibility of exotic phases with fractional excitations in two or three-dimensional systems. These examples will help us to understand how geometric frustration amplifies the effect of quantum fluctuations leading to exotic states of matter. |
