I've asked this before, but am still confused.
In AdS/CFT, a typical statement like that on p6 of Hubeny and Rangamani's http://arxiv.org/abs/1006.3675 is that a large black hole in the bulk corresponds to a thermal state in the CFT.
However, if the CFT is the complete physics, then I'd expect a bulk black hole to correspond to a boundary pure state. Takayangai and Ugajin http://arxiv.org/abs/1008.3439 have an example of this. Are there others?
Also, what is the relationship between the black hole/thermal state and black hole/pure state pictures - is every pure state "in" the boundary canonical ensemble a bulk black hole?
