DESCRIPTION:Speaker: Markus Arndt\nhosted by Onur Hosten\nAbstract: This In
 stitute Colloquium is offered as a webinar.  If you would like to attend

 61602).Throughout the last century\, quantum physics has become one of the
  most important pillars of modern  physics\, proven correct in all experi
 ments so far. And yet\, the concepts of quantum theory are contradict clas
 sical intuition\, when it comes to the notion of quantum superposition of 
 states which are regarded as mutually exclusive in the classical world. A
 n example of that is the quantum superposition principle\, which can be vi
 sualized in diffraction and interferometry of massive matter on the single
 -particle level. The discovery of matter-waves goes back to Louis de Brog
 lie who believed this concept to be universally valid. Matter-waves have 
 been demonstrated and used with electrons\, neutrons\, atoms and diatomic 
 molecules\, but is there any limit in particle mass and complexity? Why do
  we see wave-like delocalization with atoms but not with students? If qua
 ntum physics is a universally valid theory\, how can we construct experime
 nts that demonstrate and utilize it for the most universal class of partic
 les and materials?I will present a series of quantum interference experime
 nts that we have conducted at the University of Vienna to demonstrate the 
 wave nature of atoms\, fullerenes\, dye molecules\, vitamins\, peptides an
 d large organic molecules composed of up to 2000 atoms. I will discuss th
 e technological challenges and philosophical implications in these experim
 ents which we are pushing to probe the interface between quantum physics a
 nd chemistry and metrology\, biomolecular science\, gravity and the classi
 cal world.
