SUMMARY:Emergence of Quantum Order\, R. G. Herb Condensed Matter Semin
 ar\, Elio Konig \, Max Planck (Stuttgart)
DESCRIPTION:The patterns of self-organization in complex quantum syste
 ms are traditionally
\nunderstood using the concept of spontaneous sym
 metry breaking. In contrast\,
\nquantum order in the absence of symmet
 ry breaking\, in particular highly
\nentangled topologically ordered s
 tates\, describe fundamentally distinct phases
\nof matter which are o
 f great interest both in present-day condensed matter
\nresearch and i
 n quantum information science. In this talk\, I will spend some
\ntime
  reviewing the concepts of topological and non-symmetry broken quantum
 
\norder. I will then focus on the interplay of such exotic states wit
 h gapless
\nfermions\, i.e.\, metals. I will discuss their importance 
 as solid-state
\nrealizations of lattice gauge theories\, mechanisms i
 n which a Fermi sea
\nstabilizes miniature variants of topological ord
 er\, and experimental setups in
\nwhich metallic contacts are used to 
 probe quantum order. I will conclude with
\nan outlook summarizing the
  multiple synergies of quantum information theory and
\nquantum materi
 als science.
