Metal-insulator transition and magnetic ordering in Hubbard models near the Nagaoka limit

We study the metal-insulator transition and magnetic ordering in the Hubbard model using the particle-hole mapping. The analysis simplifies near the ferromagnetic limit. We find that the two dimensional(2D) Hubbard model has a charge excitation gap at half-filling for any finite U in this region on both the bipartite square lattice and the nonbipartite triangular lattice. In some cases, the system goes through a first-order phase transition to become a paramagnetic metal as $S_{z}$ is lowered. We also discuss the extension to the doped case. We find that in the large U limit, a single doped hole has a bandwidth of order of J rather than t at $S_{z}=0$.Comment: 24 pages (9 figures, available upon request), REVTE

Pseudogaps and Extrinsic Losses in Photoemission Experiments on Poorly Conducting Solids

It is shown that a photoelectron, on being emitted from a conducting solid, suffers a substantial energy change due to ohmic losses. Almost all of this energy loss takes place after the electron leaves the solid. These losses may be important in isotropic materials with relatively low conductivity, such as certain colossal magnetoresistance manganates, and in very electrically anisotropic materials such as high-T_c superconductors and 1-D conductors. In these materials, the electric field of the photoelectron can penetrate the system. These losses can drastically affect the observed lineshape on the meV scale which is now observable due to improved resolution. In particular, extrinsic losses of this type can mimic pseudogap effects and other peculiar features of photoemission in cubic manganates. This general point is illustrated with the particular case of La_{0.67}Ca_{0.33}MnO_3.Comment: 11 pages, RevTex, 2 ps figures, to be published in Science (1999), minor changes made for publicatio
