Energy Centroids in the presence of random interactions

Y. M. Zhao, A. Arima, N. Yoshida +3

In this paper we study energy centroids such as those with fixed spin and isospin, those with fixed irreducible representations for bosons, in the presence of random two-body and/o…

Diffractive $ϕ$ -meson photoproduction on proton near threshold

T. Mibe, W. C. Chang, T. Nakano +52

Photoproduction of $ϕ$ -meson on protons was studied by means of linearly polarized photons at forward angles in the low-energy region from threshold to $E_{γ}$ = 2.37 GeV. The differe…

Ring Exchange Mechanism for Triplet Superconductivity in a Two-Chain Hubbard Model: Possible Relevance to Bechgaard Salts

Y. Ohta, S. Nishimoto, T. Shirakawa +1

The density-matrix renormalization group method is used to study the ground state of the two-chain zigzag-bond Hubbard model at quarter filling. We show that, with a proper choice…

A lower bound for the number of Reidemeister moves of type III

J. Scott Carter, Mohamed Elhamdadi, Masahico Saito +1

We study the number of Reidemeister type III moves using Fox n-colorings of knot diagrams.

Energy Centroids of Spin $I$ States by Random Two-body Interactions

Y. M. Zhao, A. Arima, K. Ogawa

In this paper we study the behavior of energy centroids (denoted as $E_{I} ˉ$ ) of spin $I$ states in the presence of random two-body interactions, for systems ranging from very s…

phi photo-production from Li, C, Al, and Cu nuclei at Egamma=1.5 - 2.4 GeV

T. Ishikawa, D. S. Ahn, J. K. Ahn +39

The photo-production of $ϕ$ mesons from Li, C, Al, and Cu at forward angles has been measured at $E_{g} amma$ =1.5--2.4 GeV. The number of events for incoherent phi photo-production is…
