Query: Emergent Josephson current of $N=1$ chiral topological superconductor in
  quantum anomalous Hall insulator/superconductor heterostructures   Recently, a quantum anomalous Hall insulator (QAHI)/superconductor
heterostructure has been realized and shows half-quantized conductance plateaus
in two-terminal conductance measurements [Q. L. He \textit{et al.}, Science
{\bf357}, 294 (2017)]. The half-quantized conductance plateaus are considered
as a solid evidence of chiral Majorana edge modes. However, there is a strong
debate over the origin of the half-quantized conductance plateaus. In this
work, we propose a Josephson junction based on the QAHI/superconductor
heterostructure to identify the existence of chiral Majorana edge modes. We
find that the critical Josephson current dramatically increases to a peak value
when a half-quantized conductance plateau $\sigma_{12}=e^2/2h$ is showing up
for the $N=1$ chiral topological superconductor phase with a single chiral
Majorana mode. Furthermore, we show that the critical Josephson current of the
$N=1$ chiral topological superconductor exhibits an $h/e$-period oscillation
and is robust to disorder, in contrast to the behaviors of conventional
two-dimensional electron gas systems. We also estimate experimentally relevant
parameters and believe that the supercurrent can be observed in experiments.
