Full action of two deformation operators in the D1D5 CFT

Understand

We are interested in thermalization in the D1D5 CFT, since this process is expected to be dual to black hole formation.

• We expect that the lowest order process where thermalization occurs will be at second order in the perturbation that moves us away from the orbifold point.
• The operator governing the deformation off of the orbifold point consists of a twist operator combined with a supercharge operator acting on this twist.
• In a previous paper we computed the action of two twist operators on an arbitrary state of the CFT.
