IRLM and Kondo Correlations

In the previous chapter, we traced the history of dilute magnetic impurities in metals and quantum dots. The SIAM and Kondo models were presented, originally introduced to describe the situation. The IRLM, a simpler variant that reports the same low energy properties that are relevant in these models, was also introduced. In this chapter, general equilibrium properties of this model are discussed without and with interactions, and problems we will focus on in the following are introduced.
