Query: Second order effect of twist deformation in the D1D5 CFT   Thermalization in the D1D5 CFT should occur via interactions caused by the
twist operator, which deforms the theory off its free orbifold point. Earlier
studies investigating this deformation at first order did not show any definite
evidence of thermalization. In this paper we study the deformation to second
order, where we do expect to see the effects that should give thermalization.
We compute the effect of two twist operators on an initial vacuum state, which
generates a squeezed state analogous to the case for a single twist. We obtain
expressions for the Bogoliubov coefficients in this 2-twist case.
