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…
Dynamic Pairing Effects on Low-Frequency Modes of Excitation in Deformed Mg Isotopes close to the Neutron Drip Line
Kenichi Yoshida, Masayuki Yamagami, Kenichi Matsuyanagi
Low-frequency quadrupole vibrations in deformed Mg are studied by means of the deformed Quasiparticle-RPA based on the coordinate-space Hartree-Fock-Bogoliubov forma…
Number of Spin States of Identical Particles
Y. M. Zhao, A. Arima
In this paper we study the enumeration of number (denoted as ) of spin states for fermions in a single- shell and bosons with spin . We show that can be enum…
Energy Centroids of Spin 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 ) of spin states in the presence of random two-body interactions, for systems ranging from very s…
Simulation of Transitions between "Pasta" Phases in Dense Matter
Gentaro Watanabe, Toshiki Maruyama, Katsuhiko Sato +2
Calculations of equilibrium properties of dense matter predict that at subnuclear densities nuclei can be rodlike or slablike. To investigate whether transitions between phases wit…
Patterns of the ground states in the presence of random interactions: nucleon systems
Y. M. Zhao, A. Arima, N. Shimizu +3
We present our results on properties of ground states for nucleonic systems in the presence of random two-body interactions. In particular we present probability distributions for…
