Iterative Perturbation Theory for Strongly Correlated Electron Systems with Orbital Degeneracy
T. Saso
A new scheme of the iterative perturbation theory is proposed for the strongly correlated electron systems with orbital degeneracy. The method is based on the modified self-energy…
(2,0) Chern-Simons Supergravity Plus Matter Near the Boundary of AdS_3
N. S. Deger, A. Kaya, E. Sezgin +2
We examine the boundary behaviour of the gauged N=(2,0) supergravity in D=3 coupled to an arbitrary number of scalar supermultiplets which parametrize a Kahler manifold. In additio…
General Formula for the Magnetoresistance on the Basis of the Fermi Liquid Theory
Hiroshi Kontani
The general expression for the magnetoresistance (MR) due to the Lorentz force is derived by using the Fermi liquid transport theory based on the Kubo formula. The obtained gauge-i…
Magnetoresistance in High-Tc Superconductors: The Role of Vertex Corrections
Hiroshi Kontani
In high-Tc cuprates, the orbital magnetoresistance in plane (MR, ) is anomalously enhanced at lower tempemeratures compared with conventional Fermi liquids, and thus Kohler's…
X-ray measurements of the field and particle energy distributions in the west lobe of the radio galaxy NGC 1316 (Fornax A)
M. Tashiro, K. Makishima, N. Iyomoto +2
A follow-up X-ray study was made of the west lobe of the radio galaxy Fornax A, (NGC 1316) based on new ASCA observations made in 1997 for 98 ks, and incorporating the previous obs…
Primary proton spectrum between 200 TeV and 1000 TeV observed with the Tibet burst detector and air shower array
M. Amenomori, S. Ayabe, Caidong
Since 1996, a hybrid experiment consisting of the emulsion chamber and burst detector array and the Tibet-II air-shower array has been operated at Yangbajing (4300 m above sea leve…
