Theory of doped Mott insulators: duality between pairing and magnetism
By bosonizing the electronic t-J model exactly on any two-dimensional (2D)
lattices, and integrating out the gauge fluctuations combined to slave
particles beyond mean fields, we get a theory in terms of physical Cooper pair
and spin condensates. In the sense of mutual Berry phase they turns out to be
dual to each other. The mutual-duality is the missing key in the
resonant-valance-bond idea\cite{rvb} to work as a paradigm of doped 2D Mott
insulators. We argue that essential aspects of high- phenomenology find
natural solutions in the theory. We also provide interesting predictions for
systems on hexagonal lattices.Comment: 4 pages, no figures, Submitted to Phys. Rev. Let
Exact Results for 1D Kondo Lattice from Bosonization
We find a solvable limit to the problem of the 1D electron gas interacting
with a lattice of Kondo scattering centers. In this limit, we present exact
results for the problems of incommensurate filling, commensurate filling,
impurity vacancy states, and the commensurate-incommensurate transition.Comment: 4 pages, two columns, Latex fil
