SUMMARY:Odd Times for Triplet Pairing - Prof. James Annett\, University of
  Bristol

DESCRIPTION:The majority of known superconductors have order parameters of
  either s or d-wave pairing symmetry\, corresponding to spin-singlet Coope
 r pairs. However increasingly there is evidence that spin triplet pairing 
 may occur in a number of materials. These are therefore solid-state analog
 ues of superfluid helium-3. In particular the order parameter for triplet 
 pairing allows a complex set of phases and textures\, including topologica
 l phases. Here we discuss (1) the superconductor Sr2RuO4  which is a chira
 l paired system breaking time-reversal symmetry\, (2) other systems includ
 ing LaNiC2\, LaNiGa2 and Re6Zr where time reversal symmetry breaking has a
 lso been recently observed\,  and (3) odd-time triplet pairing induced by 
 proximity effects between a conventional s-wave superconductor and a conic
 al magnet.
