Gutzwiller Magnetic Phase Diagram of the Undoped t-t'-U Hubbard Model

R. S. Markiewicz, J. Lorenzana, G. Seibold

We calculate the magnetic phase diagram of the half-filled t-t'-U Hubbard model as a function of t' and U, within the Gutzwiller approximation RPA (GA+RPA). As U increases, the sys…

Evidence of strong correlations at the van Hove singularity in the scanning tunneling spectra of superconducting Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} single crystals

Jouko Nieminen, Ilpo Suominen, Tanmoy Das +2

We present realistic multiband calculations of scanning tunneling spectra in Bi_{2}Sr_{2}CaCu_{2} O_{8+δ} over a wide doping range. Our modeling incorporates effects of a competing…

Bulk Fermi surface and momentum density in heavily doped La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$ using high resolution Compton scattering and positron annihilation spectroscopies

W. Al-Sawai, B. Barbiellini, Y. Sakurai +13

We have observed the bulk Fermi surface (FS) in an overdoped ( $x$ =0.3) single crystal of La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$ by using Compton scattering. A two-dimensional (2D) momentum densit…
