Re: what is coulomb phase? It is a phase when unbroken U(1) has an infrared fix point, QED in the infrared is an exmaple. the potential is 1/r and the charge is not running.

Re: what is coulomb phase? infrared fix point?? 近红外不动点??请问具体是什么意思 我无知到了只懂相对论了。 http://zhangxuanzhong.blog.edu.cn/ 《相对论通俗演义》 i will love you till the null infinity.

Re: what is coulomb phase? >近红外不动点??请问具体是什么意思 ================================ it means coupling constant does not run with energy scale. For QED, this happens when the energy scale is less than the elecron mass.
