====== QFT at Finite Temperature ======

<tabbox Why is it interesting?> 
While nowadays we can use as a good approximation that the temperature is zero, in the early universe it was significantly higher. Thus, if we want to understand the fundamental interactions in the early universe, i.e. shortly after the Big Bang, we need to take into account that the temperature is non-zero.
