SUMMARY

The fractional quantum Hall effect (FQHE) is characterized as an incompressible quantum liquid, indicating that its density remains constant under external pressure. This property is crucial for understanding the unique behaviors exhibited by FQHE systems. Allan Macdonald's notes provide a detailed explanation of this concept, which can be accessed at https://arxiv.org/abs/cond-mat/9410047. The discussion emphasizes the significance of incompressibility in the context of quantum liquids.
