vacuum susceptibility Calculation
收藏 引用
Communications in Theoretical Physics 2005年 第3X期44卷 514-518页
作者: SHI Yuan-Mei PING Jia-Lun Department of Physics Nanjing Normal University Nanjing 210097 China School of Physics and Microelectronics Shandong University Jinan 250100 China
The vector susceptibility is investigated numerically in the Dyson-Schwinger approach. The results agree with those obtained analytically previously by using a simple gluon propagator.

Chinese Physics Letters 2006年 第12期23卷 3234-3237页
作者: 孙为民 宗红石 王凡 Department of Physics Nanjing University Nanjing 210093 joint Center for Particle Nuclear Physics and Cosmology Nanjing 210093 CCAST (World Laboratory) PO Box 8730 Beijing 100080
By adopting the background field method, the response of the dressed quark propagator to the presence of finite chemical potential is analysed up to the second order. From this, we obtain a model-independent formula f... 详细信息

Calculation of Particle-Number susceptibility of QED3 at Finite Temperature
收藏 引用
Chinese Physics Letters 2008年 第8期25卷 2823-2826页
作者: 胡飞 蒋宇 冯红涛 孙为民 宗红石 Department of Physics Nanjing University Nanjing 210093 Joint Center for Particle Nuclear Physics and Cosmology Nanjing 210093
Based on the external field approach and the differential form of Ward identity, we derive a more compact formula for the particle-number susceptibility in QED3 at finite temperature. Using the zero frequency approxim... 详细信息

Susceptibilities of QCD vacuum from Renormalized Dyson-Schwinger Equations]
收藏 引用
Communications in Theoretical Physics 2004年 第6期41卷 917-920页
作者: CHENWei QIShi SUNWei-Min ZONGHong-Shi DepartmentofPhysics NanjingUniversityNanjing210093China CCAST(WorldLaboratory) P.O.Box8730Beijing100080China
The pion and tensor vacuum susceptibilities are calculated in the framework of the renormalizable DysonSchwinger equations. A comparison with the results of other nonperturbative QCD approaches is given.
