Non-Abelian Strings in Hot or Dense QCD

Understand

Different types of non-Abelian vortex-strings appear in dense or hot QCD, both of which possess non-Abelian internal orientation zero modes.

• We calculate the interaction between them and find the universal repulsion for dense QCD (color superconductivity) and the dependence on the orientations for hot QCD (chirally broken phase).
• This is a review article based on our papers arXiv:0708.4092 and arXiv:0708.4096.
