Abstract 摘要 |
I will give a brief introduction on the QCD phase structure at low temperature and high baryon density, where a color superconducting phase is favored. Comparing with superconductor in condensed matter, color superconducting phase has richer structure due to the color, flavor and spin degrees of freedom. The color superconducting phase may exist in the inner core of the compact stars, where charge neutrality condition is required and one has to consider the unconventional pairing with mismatched Fermi surfaces. |
