We study the ground state properties of the one-dimensional extended-Hubbard-Kondo model at quarter-filling. This model captures the essential feature of the p-d system of organic conductors where the strongly correlated electrons interact with localized S ΒΌ 1 2 spins to bear interesting physics. It

Optinlization of the initial trial state in the ground state algorithm for the fermion simulation is performed, which quantitatively reduces the negative sign proi)lem of the Hubbard model in two dimension. Physical quantities of the Hubbard model near half-filling are calculated.
The proton spin-lattice rciaxation tirm TI has been measured in a crq'stallinc powder of Ntl&iO,: temperature to 4Β°K at Larmor frequencies of 22 and 56 hiHz. At temperatures below 20Β°K the recovery of the magnetizntion is given by z~ sum of two cxponentials, Three Tl-minima are ohserved, and one of
