The German Research Foundation DFG publishes regularly a survey of the publicly financed research in Germany, the so-called "Förderatlas". Here one also finds the total amount of grants approved to each University in each single research area. The Förderatlas 2018 (link below) reveals that in the period 2014-2016 the Saarland University ranks 2nd in the research area SND "Statistical Physics, Non-linear Dynamics, Soft Matter and Biological Physics" - with 4.8 Million Euro, behind Göttingen and before LMU Munic. This success is exclusively due to the funding of the SFB 1027 residing in the research area SND of the DFG.
