Implications of fast radio bursts for superconducting cosmic strings
  Highly beamed, short-duration electromagnetic bursts could be produced by
superconducting cosmic string (SCS) loops oscillating in cosmic magnetic
fields. We demonstrated that the basic characteristics of SCS bursts such as
the electromagnetic frequency and the energy release could be consistently
exhibited in the recently discovered fast radio bursts (FRBs). Moreover, it is
first showed that the redshift distribution of the FRBs can also be well
accounted for by the SCS burst model. Such agreements between the FRBs and SCS
bursts suggest that the FRBs could originate from SCS bursts and thus they
could provide an effective probe to study SCSs. The obtained values of model
parameters indicate that the loops generating the FRBs have a small length
scale and they are mostly formed in the radiation-dominated cosmological epoch.
