Abstract
We investigate the nuclear and quark matters at finite real chemical potential () and low temperature from the viewpoint of the canonical sectors constructed via the imaginary chemical potential region. Based on the large estimation, where is the number of colors, we can discuss the confinement-deconfinement nature at finite from the canonical sectors. We find the expectation that the sharp changes of canonical sectors at , where is the lowest baryon mass, happens in the large regime, and it is matched with the quarkyonic picture. In addition, we discuss the color superconductivity and the chiral properties from the structure of canonical sectors. Even in the present anatomy from the canonical sectors, we obtain a suitable picture for the dense QCD matter.
