Metal Enrichment of Ly alpha Clouds and Intergalactic Medium
Izumi Murakami, Kazuyuki Yamashita
We have examined the metal enrichment of the intergalactic medium (IGM) based on a galactic wind model. A galactic wind driven by supernovae brings metallic gas to the IGM but not…
Abelian-Projected Effective Gauge Theory of QCD with Asymptotic Freedom and Quark Confinement
Kei-ichi Kondo
Starting from SU(2) Yang-Mills theory in 3+1 dimensions, we prove that the abelian-projected effective gauge theories are written in terms of the maximal abelian gauge field and th…
Monte-Carlo Simulation for an Aerogel Cherenkov Counter
Ryuji Suda et al
We have developed a Monte-Carlo simulation code for an aerogel \v Cerenkov Counter which is operated under a strong magnetic field such as 1.5T. This code consists of two parts: ph…
Bogoliubov quasiparticle spectra of the effective d-wave model for cuprate superconductivity
Y. Ohta, M. Yamaguchi, R. Eder
An exact-diagonalization technique on finite-size clusters is used to study the ground state and excitation spectra of the two-dimensional effective fermion model, a fictious model…
Total and Parity-Projected Level Densities of Iron-Region Nuclei in the Auxiliary Fields Monte Carlo Shell Model
H. Nakada, Y. Alhassid
We use the auxiliary-fields Monte Carlo method for the shell model in the complete -shell to calculate level densities. We introduce parity projection techniques whi…
Landau mapping and Fermi liquid parameters of the 2D t-J model
S. Nishimoto, Y. Ohta, R. Eder
We study the momentum distribution function n(k) in the 2D t-J model on small clusters by exact diagonalization. We show that n(k) can be decomposed systematically into two compone…
