The intricate interplay of band-formation and electron correlation effects in uranium heavy fermion compounds is subject of an ongoing debate. Here scientists from MPI CPfS in Dresden, University of Cologne, University of Erlangen, Heidelberg University, University of California at San Diego, Los Alamos National Laboratory, Institute of Low Temperature & Structure Research in Wroclaw, Van-der-Waals-Zeeman Institute in Amsterdam, and the German Synchrotron in Hamburg (PETRA-III/DESY) gained new and unexpected insight from advanced spectroscopies on isostructural members of the UM2Si2 family with different properties.
