Triaxial dynamics in the quadrupole-deformed rotor
《Chinese Physics C》2016年第1期47-54,共8页李秋月 王晓霞 左岩 张宇 潘峰 
Supported by National Natural Science Foundation of China(11375005,11005056,11175078)
The triaxial dynamics of the quadrupole-deformed rotor model of both the rigid and the irrotational type are investigated in detail. The results indicate that level patterns of the two types of model can be matched wi...

Shape phase transition in the odd Sm nuclei: effective order parameter and odd–even effect
《Chinese Physics C》2015年第10期48-54,共7页张宇 关鑫 王印 左岩 包丽娜 潘峰 
Supported by National Natural Science Foundation of China(11375005,11005056,11175078,11405080)
Some binding energy related quantities serving as effective order parameters have been used to analyze the shape phase transition in the odd Sm nuclei. It is found that the signals of phase transition in the odd Sm nu...

U(2)振动子模型中的量子相变与临界点对称性
《中国科学:物理学、力学、天文学》2014年第5期501-505,共5页张宇 赵允 安阳 李盛新 徐佳 于东麒 
国家自然科学基金资助项目(批准号:11005056;11375005)
本文研究了U(2)振动子模型在大N极限以及有限N情况下的量子相变行为,并讨论了临界点对称性概念在一维系统中的适用性.通过对U(2)振动子模型的势能结构,低激发谱等动力学性质的分析,我们发现系统在临界点处是最容易激发的,其低激发动力...

从二次量子化角度看一维无限深方势阱问题被引量:1
《大学物理》2013年第9期28-30,共3页张宇 潘峰
