Shape Phase Transition of the Axially Symmetric States Between the U(5) and SU(3) Symmetries
Liang-zhu Mu, Yu-xin Liu
The shape phase structure and its transition of the nucleus in the transitional region between the U(5) and SU(3) symmetries is restudied within the framework of coherent-state the…
Approach to the Rotation Driven Vibrational to Axially Rotational Shape Phase Transition Along the Yrast Line of a Nucleus
Yu-xin Liu, Liang-zhu Mu, Haiqing Wei
By analyzing the potential energy surface, the shape phase diagram and the energy spectrum of the nucleus in U(5) symmetry in the IBM, we propose that the U(5) symmetry with parame…
Approach to Vibrational to Axially Rotational Shape Phase Transition Along the Yrast Line
Yu-xin Liu, Liang-zhu Mu
With the energy surface of the nucleus in U(5) symmetry being analyzed in the framework of thermodynamics, the vibration and rotation phase diagram in terms of the angular momentum…
Low-lying States of He and Be in Nodal Surface Structure Analysis
Yu-xin Liu, Jing-sheng Li, Cheng-guang Bao
The low-lying states of light nuclei He and Be are studied. Using the inherent nodal surface(INS) analysis approach, we deduce the quantum numbers and the spatial symmetrie…
Statistical Properties of E(5) and X(5) Symmetries
Jing Shu, Hong-Bo Jia, Yu-Xin Liu
We study the energy level statistics of the states in E(5) and X(5) transitional dynamical symmetries. The calculated results indicate that the statistics of E(5) symmetry is regul…
A Nonlinear Realized Approach of SU(2) Chiral Symmetry Spontaneous Breaking and Properties of Nuclear Matter
Xiao-Fu Lu, Bao-Xi Sun, Yu-Xin Liu +2
A nonlinear realization of SU(2) chiral symmetry spontaneous breaking approach is developed in the composite operator formalism. A Lagrangian including quark, gluon and Goldstone b…
