  • In this paper an overview is given of some recent issues and results concerning the single-particle electronic structure of strongly correlated electron systems. Specific topics include the {alpha} {minus} {gamma} transition in cerium metal, the Kondo resonance in Y{sub 1{minus}x}U{sub x}Pd{sub 3} and the insulator-to-metal transition in superconducting cuprates.
  • The Quasimolecular Model using a Two Centre basis to describe the electronic emitting structure gives an alternative treatment of line broadening in dense and hot plasmas. Two codes are developed: IDEFIX for the radiative properties, QMSPECTRA (postprocessed to the first one) for the spectral line shapes. The observability of dense plasma effects (PPS, asymmetries and satellite features) in spectroscopic measurements is analysed within the proposed model and taking care of the eventual integrations over density gradients.
  • A square-lattice gauge-theory model for the holon liquid existing in the unconventional metallic phases of strongly interacting two-dimensional electron liquids is introduced. The phase of the holon order parameter couples in a gauge-invariant way to a statistical gauge field, which arises from strong-interaction physics. We find that the superfluid transition that exists in the absence of statistical gauge-field excitations in the holon liquid turns into a crossover phenomenon in the presence of such fluctuations. The corresponding high-temperature phase shows a [ital T]-linear resistance, while the low-temperature phase exhibits a [ital T][sup 2] dependence for the resistance. The crossover temperature scalemore » [ital T][sub [ital c]0] [ital vanishes], however, in the limit of maximum statistical fluctuations. While we find that statistical gauge-field excitations are strictly gapless, the residue of the pole corresponding to such excitations becomes exponentially small at temperatures small in comparison to [ital T][sub [ital c]0].« less
  • We present a new model describing strongly correlated electrons on a general {ital d}-dimensional lattice. It is an extended Hubbard model and it contains the {ital t}-{ital J} model as a special case. The model naturally describes local electron pairs, which can move coherently at arbitrary momentum. By using an {eta}-pairing mechanism we can construct eigenstates of the Hamiltonian with off-diagonal long-range order. In the attractive case the exact ground state is superconducting in any number of dimensions. On a one-dimensional lattice, the model is exactly solvable by Bethe ansatz.
  • The density response function {ital N}({bold q},{omega}) of the two-dimensional {ital t}-{ital J} model is studied starting from a mixed- gauge formulation of the slave-boson approach. Our results for {ital N}({bold q},{omega}) are in remarkable agreement with exact diagonalization studies, and provide a natural explanation of the anomalous features in the density response in terms of the spin-polaron nature of the charge carriers. In particular, we have identified unexplained low-energy structures in the diagonalization data as arising from the coherent polaron motion of holes in a spin liquid. {copyright} {ital 1996 The American Physical Society.}
