Abstract: It is very intriguing to investigate the properties of QCD matter at finite baryon number density since it is not only the question of particle physics but also that of astrophysics, which is associated with compact stars, supernova explosions and gravity waves.

In the first part of this talk, I present some studies of the QCD phase diagram, based on the effective field theory such as the Ginzburg-Landau model as well as the gauge/gravity duality.

Here I show how the interplay between the order parameters such as chiral and diquark condensates as well as the QCD axial anomaly plays a crucial role.

In the second part, as an application of the study for dense matter, I consider the issue on dark matter capture in neutron stars and show some preliminary results.
