Summary: The generating functional of a Euclidean quantum ﬁeld theory in dspace dimensions can alternatively be interpreted as a partition sum in a classicalstatistical model in d dimensions. The corresponding inverse temperature is thenrelated to Planck’s constant by b ˘1/¯h. I See also: Discussions like these can be found in many places, e.g. chapter 2 of thebook by Smit [10] or chapter V.2 of the book by Zee [13]. 1.3. Finite temperature quantum ﬁeld theory In standard quantum ﬁeld theory…
