Correlation Functions,ckets denote an average for the equilibrium system at either zero or finite temperature. Although at first sight this function appears to be of rather limited use, it will turn out that, on the contrary, correlation functions are a very powerful device and are heavily used in a variety of problems.

Thermal Effects in Nano Optics,ic, in this book we only provide a brief introduction and refer the interested reader to the rich literature on the subject. In Chap. . we have seen that electromagnetic fields transport energy and momentum, as described by the flow of the Poynting vector and Maxwell’s stress tensor. Similarly, in t

Two-Level Systems,s. As a starting point, we introduce the simplest model of a two-level system, which will allow us to develop a pictorial representation of the system state in terms of a Bloch vector. The generalization to few-level systems will be discussed in the next chapter, where we will also present examples

Unfortunately, it turns out that we cannot easily extend the Bloch vector formalism to a higher number of states, and we thus hav
