We propose a mechanism to solve the missing pulsar problem, a puzzle created by the failed expectation to observe a large number of pulsars within the distance of 10 pc of the galactic center. Pulse observations of the magnetar SGR J1745-2900 indicate that magnetar formation should be efficient in the center of the galaxy, so the low abundance observed in the region underlines that some suppression effect must be operating that leads to short-lived magnetars. The proposed mechanism is based on the idea that if magnetars created in the galaxy center are hybrid stars with a core of quark matter in the so-called magnetic dual chiral density wave phase, their exposure to γ-ray burst radiation produce hybridized modes of photons and axions, known as axion-polaritons, which contribute to the magnetar mass and induce its collapse into a black hole.
