DESCRIPTION:Kevin Huguenin-Dumittan\nAt times\, surprisingly simple mathem
 atical models such as the Ising model can predict properties of macroscopi
 c systems to multiple digits of accuracy. This is despite of the fact that
  in reality\, many of these material properties arise from a much more com
 plex interplay at the electronic structure level. Moreover\, it can even b
 e observed that the behavior of many seemingly unrelated systems can be de
 scribed quantitatively by the same models\, a phenomenon often called univ
 ersality.\nSuch behavior and much more can be understood using the renorma
 lization group\, more correctly the renormalization "semi"group. It is a p
 owerful mathematical technique used in various subfields of theoretical ph
 ysics: quantum field theory\, statistical mechanics and condensed matter p
 hysics. The session will provide a short introduction into this vast field
 \, using the theory of phase transitions as the primary example. Due to th
 e diverse background (math\, physics\, chemistry\, MSE\, etc.) of the audi
 ence\, we will start with a more thorough motivation of the underlying ide
 as and prerequisites\, slowly moving towards a more mathematical treatmen
 t of the renormalization group.\n\nReferences:\n1. Humphrey J. Maris and L
