Quantum simulator for the $\f{O(3)}$ nonlinear sigma model
  We propose a design for the construction of a laboratory system based on present-day technology which reproduces and thereby simulates the quantum dynamics of the O(3) nonlinear sigma model. Apart from its relevance in condensed-matter theory, this strongly interacting quantum field theory serves as an important toy model for quantum chromo-dynamics (QCD) since it reproduces many crucial properties of QCD.
