SUMMARY:Topological Matter and Why You Should Be Interested - Steve Simon

DESCRIPTION:In two dimensional topological phases of matter\, processes de
 pend on gross topology rather than detailed geometry. Thinking in 2+1 dime
 nsions\, particle world lines can be interpreted as knots or links\, and t
 he amplitude for certain processes becomes a topological invariant of that
  link. While sounding rather exotic\, we believe that such phases of matte
 r not only exist\, but have actually been observed in quantum Hall experim
 ents\, and could provide a uniquely practical route to building a quantum 
 computer.   Possibilities have also been proposed for creating similar phy
 sics in systems ranging from superfluid helium to strontium ruthenate to s
 emiconductor-superconductor junctions to quantum wires to spin systems to 
 cold atoms.
