Strongly correlated electron systems: theory and simulation; Motivated by several anomalous experimental properties observed in the high temperature superconductor compounds, our group is intensively studing the phase diagram of strongly correlated electron systems, such as the t-J model and the Hubbard model in low spatial dimensions or for weakly coupled planes or chains. excitation spectrum L2/2J, the moment of inertia J being of order N (macroscopically large when N!‘). The low-energy excitation spectrum of this heavy rigid rotor above the ground-statesL=0d is essentially gapless (i.e., continu-ous). Thus although the formal ground state posseses con-tinuous rotational symmetry (i.e., L=0), “there is a

6.8 Correlated Excited State Methods: The ADC() FamilyThe ADC() family of correlated excited state methods is a series of size-extensive excited state methods based on perturbation theory.Each order of ADC presents the excited state equivalent to the well-known th order Møller-Plesset perturbation theory for the ground state. Currently, the ADC variants ADC(0), ADC(1), ADC(2)-s, ADC(2)-x and Strongly correlated electron systems: theory and simulation; Motivated by several anomalous experimental properties observed in the high temperature superconductor compounds, our group is intensively studing the phase diagram of strongly correlated electron systems, such as the t-J model and the Hubbard model in low spatial dimensions or for weakly coupled planes or chains.

We focus our study on the effects of electron-electron and electron-phonon correlations in the various competing symmetry-breaking phases in the ground state, as well as the topological excitations corresponding to local defect states of the system which determine the optical and transport properties, and doping behavior of the system.

The interplay of strong electron-electron correlation and electron-phonon (EP) interaction has recently attracted much attention.1) One of the issues is to under-stand the effect of the EP interaction on carriers introduced into a Mott insulator. In the ground state of the Mott insulator, the on-site Coulomb repulsion makes the

The simplest model of a strongly correlated electron system coupled to the lattice is given by the single-band Hubbard-Holstein (HH) model. In this work, the HH model is not used as a microscopic model for the cuprates, but rather as an idealized description of the … Excited states of boron isoelectronic series from explicitly correlated wave functions F. J. Gálvez and E. Buendía The ground state and some low-lying excited states arising from the 1s22s2p2 configuration of the Two-electron properties can be studied in terms of both the interelectronic, or intracule,
