1) My main research interest for recent couple of years was (and is) the
   extended 2D t-J model at very small doping near half filling.
   I strongly believe that in LSCO we fully understood nature of the
   Neel -> spin-glass transition at 2% doping and the spin-glass ->
   superconductor transition at 5.5% doping.
   Actually the understanding is more general than just LSCO, but some
   properties depend on the specific way of doping.
   I am very interested to give a talk on this topic. Would it be possible?
   This is the analytical work, practically no numerics.

2) We have been working for many years on 2D J1-J2 model, and as many
   other people we have been especially interested in the nature of the
   Neel -> Dimer-solid  transition at J2/J1=0.4.
   During last year we practically closed the problem. Unfortunately the
   conclusion is rather boring: this is the first order phase transition.
   This is mainly numerical work involving series expansions.

3) This is pretty far from the topic of the present program, but still
   to give a full picture I also would like to mention our work on searches
   of fundamental time-parity violations in solids. This is similar to searches
   of the neutron electric dipole moment in reactor experiments,  but
   solids can give a huge gain in sensitivity compared to beam and trap
   experiments.
   Certainly we do not perform the "searches", we do theory, and there are
   experimental groups doing the "searches".
