DESCRIPTION:Prof. Markus Greiner\, associate professor of physics\, Harvar
 d University\nUnderstanding the behaviors of strongly-interacting spin sys
 tems is one of the central objectives of modern manybody quantum physics. 
 I will present experiments in which we have realized quantum magnetism wit
 h ultracold atoms in an optical lattice. We carry out a quantum simulation
  of an Ising spin chain and demonstrate a quantum phase-transition from a 
 paramagnetic phase to an anti-ferromagnetic phase. The magnetic phases are
  detected in situ through our quantum gas microscope.  This work opens a w
 ide range of new possibilities for studying quantum magnetism. Exotic stat
 es of matter and frustrated spin physics in optical lattices are now withi
 n experimental reach.
