Résumé |
The D1D5 CFT is a holographic dual of a near-extremal black hole in string theory. The process of black
hole formation in the bulk is dual to a process of thermalization in the CFT. It is desirable to have a
detailed understanding of this thermalization process. The interaction in the CFT involves a twist operator
which joins together different copies of a free CFT. I will describe recent results which derive the effect of
this interaction when it links together CFT copies with winding numbers M and N to produce a copy with
winding M+N, populated with excitations of a particular form. These results are a step towards
understanding the thermalization process in the D1D5 CFT.
