The information paradox and the infall problem
Samir D. Mathur
It is sometimes believed that small quantum gravity corrections to the Hawking radiation process can encode the correlations required to solve the black hole information paradox. R…
Membrane paradigm realized?
Samir D. Mathur
Are there any degrees of freedom on the black hole horizon? Using the `membrane paradigm' we can reproduce coarse-grained physics outside the hole by assuming a fictitious membrane…
Unwinding of strings thrown into a fuzzball
Stefano Giusto, Samir D. Mathur
The traditional black hole has a horizon, with a singularity inside the horizon. But actual microstates of black holes are `fuzzballs', with no horizon and a complex internal struc…
Excitations in the deformed D1D5 CFT
Steven G. Avery, Borun D. Chowdhury, Samir D. Mathur
We perform some simple computations for the first order deformation of the D1D5 CFT off its orbifold point. It had been shown earlier that under this deformation the vacuum state c…
Deforming the D1D5 CFT away from the orbifold point
Steven G. Avery, Borun D. Chowdhury, Samir D. Mathur
The D1D5 brane bound state is believed to have an `orbifold point' in its moduli space which is the analogue of the free Yang Mills theory for the D3 brane bound state. The supergr…
