DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QM3/19/">Ber
 ry's Phase\, TKN$^2$ Integers and All That: My work on Topology in Condens
 ed Matter</a>\nby Barry Simon (Caltech) as part of Quantum Matter meets Ma
 ths (IST\, Lisbon)\n\n\nAbstract\nI will give an overview of my work on to
 pological methods in condensed matter physics almost 40 years ago. Include
  will be Homotopy and TKN$^2$ integers\, holonomy and Berry's phase and qu
 arternions and Berry's phase for Fermions. If time allows\, I'll discuss s
 upersymmetry and pairs of projections.\n
