DESCRIPTION:Speakers: Hanns-Christoph Nägerl (University of Innsbruck\, A
 ustria)\n\nSince the formation of atomic Bose-Einstein condensates (BEC) a
 bout 30 years ago\, systems of cold atoms have developed into a versatile 
 playground for the investigation into quantum many-body physics\, with the
  promise to shed light onto dynamical processes in the spirit of quantum s
 imulation efforts. With exquisite parameter control and a broad range of d
 etection methods\, a multitude of phenomena\, ranging from superfluidity a
 nd quantum phase transitions to supersolidity and quantum transport\, can 
 be probed with high precision. I will give a broad introduction to the fie
 ld of cold atoms and its techniques\, and then turn to a selected set of e
 xperiments from my group that address various dynamical quantum many-body 
 phenomena such as dynamical localization in 1D [1] and\, surprisingly\, al
 so in 3D [2]\, anyonization of bosons [3]\, fractional Fermi seas [4]\, Be
 the strings [5] and dissipationless flow beyond the Landau paradigm [6].\n
