Comment on "Searching for Topological Defect Dark Matter via Nongravitational Signatures"

P. P. Avelino, L. Sousa, F. S. N. Lobo

Abstract
In the letter by Stadnik and Flambaum [Phys. Rev. Lett. 113, 151301 (2014)] it is claimed that topological defects passing through pulsars could be responsible for the observed pulsar glitches. Here, we show that, independently of the detailed network dynamics and defect dimensionality, such proposal is faced with serious difficulties.
