  In the D1D5 CFT the twist operator of order 2 can twist together two copies
in the untwisted sector into a single joined copy in the twisted sector.
Traditionally, this effect is computed by using the covering map method.
Recently, a new method was developed using the Bogoliubov ansatz and conformal
symmetry to compute this effect in a toy model of one free boson. In this
paper, we use this method with superconformal symmetry to compute the effect of
the twist operator in the D1D5 CFT. This may provide more effective tools for
computing correlation functions of twist operators in this system.
