SPRINGERBRIEFS IN PHYSICS EMERGENCE OF TEMPER...

Field theory  relying on the concept of continuous space and time while confronted with the
quantum physical nature of observable quantities  still has some fundamental challenges to
face. One such challenge is to understand the emergence of complexity in the behavior of
interacting elementary fields  including among other things nontrivial phase structures of
elementary matter at high energy density or an atypical emergence of statistical properties 
e.g.  when an apparent temperature is proportional to a constant acceleration in a homogeneous
gravitational field. Most modern textbooks on thermal field theory are mainly concerned with
how the field theory formalism should be used if a finite temperature is given. In contrast 
this short primer explores how the phenomenon of temperature emerges physically for elementary
fields - inquiring about the underlying kinetic field theory and the way energy fluctuations
and other noise should be handled - and it investigates whether and how this harmonizes with
traditional field theory concepts like spectral evolution  the Keldysh formalism  and phase
transitions.
