Revisiting the Vector and Axial-vector Vacuum Susceptibilities
Lei Chang, Yu-xin Liu, Wei-min Sun +1
We re-investigate the vector and axial-vector vacuum susceptibilities by taking advantage of the vector and axial-vector Ward-Takahashi identities. We show analytically that, in th…
The calculation of the equation of state of QCD at finite chemical potential and zero temperature
Hong-shi Zong, Wei-min Sun
In this paper, we give a direct method for calculating the partition function, and hence the equation of state (EOS) of Quantum Chromodynamics (QCD) at finite chemical potential an…
Reply to the Comment on "Spin and orbital angular momentum in gauge theories: Nucleon spin structure and multipole radiation revisited" [PRL 100:232002 (2008)]
Xiang-Song Chen, Xiao-Fu Lü, Wei-Min Sun +2
This is a Reply to the Comment [arXiv:0807.0699] on our paper [PRL 100:232002 (2008)].
Spin and orbital angular momentum in gauge theories: Nucleon spin structure and multipole radiation revisited
Xiang-Song Chen, Xiao-Fu Lü, Wei-Min Sun +2
We address and solve the long-standing gauge-invariance problem of the nucleon spin structure. Explicitly gauge-invariant spin and orbital angular momentum operators of quarks and…
Testing the correctness of the Poynting vector \vec E\times\vec B as the momentum density of gauge fields
Xiang-Song Chen, Xiang-Bai Chen, Wei-Min Sun +1
Following our recent finding that the renowned formula is not the correct density for the electromagnetic angular momentum, here we examine the…
Spin and orbital angular momentum in gauge theories (I): QED and determination of the angular momentum density
X. S. Chen, X. F. Lü, W. M. Sun +2
This two-paper series addresses and fixes the long-standing gauge invariance problem of angular momentum in gauge theories. This QED part reveals: 1) The spin and orbital angular m…
