On the correspondence between mirror-twisted sectors for N=2   supersymmetric vertex operator superalgebras of the form $V \otimes V$ and   N=1 Ramond sectors of $V$
  Using recent results of the author along with Vander Werf, we present the classification and construction of mirror-twisted modules for N=2 supersymmetric vertex operator superalgebras of the form $V \otimes V$ for the signed transposition mirror map automorphism. In particular, we show that the category of such mirror-twisted sectors for $V\otimes V$ is isomorphic to the category of N=1 Ramond sectors for $V$.
