CLUSTERING PHENOMENON BY RANDOM TWO-BODY INTERACTIONS AND THE J max PAIRING INTERACTION

Y. M. Zhao, Akito Arima

Published Jul 10, 2005• 0 citations
Publisher

Abstract

In this talk we first explain the context of a topic called "regularities for many-body systems in the presence of random two-body interactions". Then we discuss the robustness of the α clustering phenomenon in the presence of random two-body interactions. Last, we discuss a clustering picture of fermions in a single-j shell with the J max pairing interaction.

Many-body systems in the presence of the random interactions and the J pairing interaction

Akito Arima

In this talk I shall discuss some regularities of many‐body systems in the presence of random interactions and regularities of a single‐j shell for the J pairing interaction which works only when two particles are coupled to spin J. I shall first explain an empirical rule to predict the spin I ground state probability. Then I shall present some interesting results of a single‐j shell under the J pairing interaction. Last I shall discuss some preliminary results of binding energies in the presence of random two‐body interactions.

REGULAR LOW-LYING STRUCTURE OF ATOMIC NUCLEI UNDER RANDOM INTERACTIONS

Y. M. Zhao

In this paper we present a brief discussion on regular low-lying structures of many-body systems generated from random two-body interactions. In particular, we discuss the famous problem of spin zero ground state dominance, regularities of energy centroids and collectivity in the presence of random interactions.

Collective behavior in random interaction

Calvin W. Johnson, Hai Ah Nam

Recent investigations have looked at the many-body spectra of random two-body interactions. In fermion systems, such as the interacting shell model, one finds pairing-like spectra, while in boson systems, such as IBM-1, one finds rotational and vibrational spectra. We discuss the search for random ensembles of fermion interactions that yield rotational and vibrational spectra, and in particular present results from a new ensemble, the ``random quadrupole-quadrupole ensemble''

J-Pairing Interractions of Fermions in a Single-J Shell

A. Arima

In this talk I shall introduce our recent works on general pairing interactions and pair truncation approximations for fermions in a single- j shell, including the spin zero dominance, and features of eigenvalues of fermion systems in a single- j shell interacting by a J -pairing interaction.
