Correlation Diagrams: An Intuitive Approach to Interactions in Quantum Hall Systems

In this chapter, we study correlations resulting from Coulomb interactions in fractional quantum Hall systems. Our objective is to use correlation diagrams Correlation diagram to gain new insights into correlations in strongly interacting many-body systems. We introduce correlation diagrams to guide in the selection of the correlation functions correlation function caused by interactions. Electrons are represented by points located at positions $$z_{i}$$ in the complex plane, and there are correlation lines connecting pairs of electrons. A correlation line connecting particles i and j represents a correlation factor (cf) Correlation factor .
