Abstract

The quantum shape phase transition between the spherical and deformed γ-unstable (U(5)O(6)) even-even nuclei within the frameworks of Interacting Boson Model-1 and 2 (IBM-1,2) for low-lying states, using the “entanglement entropy” (S) has been studied. In both frameworks, the theoretical results showed that there exist minimum and maximum entanglement values between s bosons in the U(5) and O(6) limits, respectively. In order to confirmation of the theoretical results, we have calculated and analyzed the entanglement entropy of sd bosons and proton (π) - neutron (ν) bosons in Cerium (C58122136e) isotopes. The results indicate that the entanglement entropy correctly describes the transition from U(5) to O(6), for ground state (01+), but it cannot accurately determine the transitional nucleus.

相互作用玻色子模型-2(IBM-2)中 SO(6)-U(5) 过渡核的量子纠缠
在相互作用玻色子模型-1 和 2(IBM-1,2)的框架内,利用 "纠缠熵"(S)研究了球形和变形γ-不稳定(U(5)-O(6))偶偶核之间对于低洼态的量子形状相变。在这两个框架中,理论结果表明,在 U(5) 和 O(6) 限度下,s 玻色子之间分别存在最小和最大纠缠值。为了证实理论结果,我们计算并分析了铈(C58122-136e)同位素中 s-d 玻色子和质子(π)- 中子(ν)玻色子的纠缠熵。结果表明,纠缠熵正确地描述了基态(01+)从U(5)到O(6)的转变,但它不能准确地确定过渡核。
