Abstract
The occupied Landau levels of strange quark matter are investigated in the framework of the SU(3) NJL model with a conventional coupling and a magnetic-field dependent coupling respectively. At lower density, the Landau levels are mainly dominated by and quarks. Threshold values of the chemical potential for the quark onset are shown in the plane. The magnetic-field-dependent running coupling can broaden the region of three-flavor matter by decreasing the dynamical masses of quarks. Before the onset of quarks, the Landau level number of light quarks is directly dependent on the magnetic field strength by a simple inverse proportional relation with , which is approximately 2 times of quarks at a common chemical potential. When the magnetic field increases up to , almost all three flavors are lying in the lowest Landau level.
