In this talk, I will review recent developments of strongly correlated electron systems in transition metal materials. In particular, transition metal oxides exhibit novel quantum phases including unconventional superconductivity, electronic nematic phases, topological Mott insulators, and quantum spin liquids. This rich variety of phenomena stems from the interplay among charge, spin,...

We consider the one dimensional spin chain similar to the one studied by Haldane, however in the opposite limit, of very large anisotropy and small nearest neighbour, anti-ferromagnetic exchange coupling between the spins. The zero order theory has a ground state that is 2^N degenerate, corresponding to each spin in its highest or lowest weight state. For a periodic chain with an even number...

A dimensional regularization scheme for
quantum field theories with Fermi surface is proposed
to study scaling behaviour of non-Fermi liquid states
in a controlled approximation.
Starting from a Fermi surface in two space dimensions,
the co-dimension of Fermi surface is extended to
a general value while the dimension of Fermi surface is fixed.
When Fermi surface is coupled with a...

A nonequilibrium thermodynamic theory demonstrating an induction effect of a statistical nature will be presented. We have shown that this thermodynamic induction can arise in a class of systems that have variable kinetic coefficients (VKC). In particular if a kinetic coefficient associated with a given thermodynamic variable depends on another, faster, thermodynamic variable then we have...
