Lifting of level-1 states in the D1D5 CFT
Bin Guo, Samir D. Mathur
The D1D5 CFT has a large set of states that are supersymmetric at the `free' orbifold point in moduli space. When we perturb away from this point, some of these states join into lo…
Thermalization in the D1D5 CFT
Shaun Hampton, Samir D. Mathur
It is generally agreed that black hole formation in gravity corresponds to thermalization in the dual CFT. It is sometimes argued that if the CFT evolution shows evidence of large…
The nature of the gravitational vacuum
Samir D. Mathur
The vacuum must contain virtual fluctuations of black hole microstates for each mass . We observe that the expected suppression for is counteracted by the large numbe…
Lifting of states in 2-dimensional supersymmetric CFTs
Bin Guo, Samir D. Mathur
We consider states of the D1-D5 CFT where only the left-moving sector is excited. As we deform away from the orbifold point, some of these states will remain BPS while others can `…
