 abstract = {Rare earth manganites doped with alkaline earths, namely
Re(1-x)A(x)MnO(3), exhibit colossal magnetoresistance, metal insulator
transitions, competing magnetic, orbital and charge ordering, and many
other interesting but poorly understood phenomena. In this article I
outline our recent theory based on the idea that in the presence of
strong Jahn-Teller, Coulomb and Hund's couplings present in these
materials, the low-energy electronic states dynamically reorganize
themselves into two sets: one set (l) which are polaronic, i.e.,
localized and accompanied by large local lattice distortion, and another
(b) which are non-polaronic and band-like. The coexistence of the
radically different e and b states, and the sensitive dependence of
their relative energies and occupation upon doping x, temperature T,
magnetic field H, etc., underlies the unique effects seen in manganites.
I present results from strong correlation calculations using dynamical
mean-field theory and simulations on a new 2-fluid model which accord
with a variety of observations.},
