| 中文摘要 | We investigated two pion condensed phases in the frame of two flavor Nambu-Jona-Lasinio model at finite baryon density: the homogeneous and isotropic Sarma phase and inhomogeneous and anisotropic LOFF phase. At small isospin chemical potential mu(1), the Sarma state is free from the Sarma instability and magnetic instability due to the strong coupling and large enough effective quark mass. At large mu(1), while the Sarma instability can be cured via fixing baryon density n(B) to be nonzero, its magnetic instability implies that the LOFF state is favored than the Sarma state. In the intermediate mu(1) region, the stable ground state is the Sarma state at higher n(B) and LOFF state at lower n(B).; Chinese Acad Sci, Shanghai Inst Appl Phys |
