SUMMARY:Search for Time-Reversal-Symmetry-Breaking Effects in Unconven
 tional Superconductors\, Physics Department Colloquium\, Aharon Kapitu
 lnik\, Stanford University
DESCRIPTION:BCS theory of conventional superconductivity can be descri
 bed by a condensate of Cooper-pairs of time-reversed states. Such supe
 rconductors respect time reversal symmetry and are immune against non-
 magnetic scattering (the Anderson theorem). However\, for unconvention
 al superconductors\, which do not respect Anderson theorem\, there can
  be a class of superconductors with "chiral" order parameter for which
  time-reversal symmetry is broken (TRSB). In this talk we will review 
 our recent studies of TRSB in several systems\, emphasizing possible t
 riplet superconductors such as Sr2RuO4\, the study of the pseudogap st
 ate of high temperature superconductors\, and the inverse proximity ef
 fect in superconductor/ferromagnet bilayer structures. <br>
