We perform a comprehensive numerical study of gravitational waves from stellar core collapse in the massive scalar-tensor theory with the cubic and quartic self-interactions of the scalar field. We investigate the dependence of gravitational waves on the self-interaction as well as the mass of the scalar field and the conformal factor. We find that gravitational-wave spectra show a systematic difference between the cubic and quartic self-interactions. We also find that this systematic difference is insensitive to the mass of the scalar field and the conformal factor. Our results indicate that the type of the self-interaction could be constrained by observations of gravitational waves using the future-planned detectors.

Mass spectra and Mott transition of pions $(pi^0, pi^pm)$ at finite temperature and magnetic field are investigated in a two-flavor NJL model, and we focus on the inverse magnetic catalysis (IMC) effect and current quark mass (CQM) effect. Due to the dimension reduction of the constituent quarks, the pion masses jump at their Mott transitions, which is independent of the IMC effect and CQM effect. We consider the IMC effect by using a magnetic dependent coupling constant, which is a monotonic decreasing function of magnetic field. With IMC effect, the Mott transition temperature of $pi^0$ meson $T_m^0$ is a monotonic decreasing function of magnetic field. For charged pions $pi^{pm}$, the Mott transition temperature $T_m^+$ fast increases in weak magnetic field region and then decreases with magnetic field, which are accompanied with some oscillations. Comparing with the case without IMC effect, $T_m^0$ and $T_m^+$ are lower when including IMC effect. CQM effect are considered by varying parameter $m_0$ in non-chiral limit. For $pi^0$ meson, $T_m^0$ is not a monotonic function of magnetic field with low $m_0$, but it is a monotonic decreasing function with larger $m_0$. In the weak magnetic field region, $T_m^0$ is higher for larger $m_0$, but in the strong magnetic field region, it is lower for larger $m_0$. For $pi^+$ meson, $T^+_m$ is only quantitatively modifies by current quark mass effect, and it becomes higher with larger $m_0$.
