High Energy Reflection Coefficients of Black Holes and Branes
Roi Basha, Nissan Itzhaki, Lior Liram
We study the reflection coefficient associated with a wave that scatters off various black holes in general relativity. We show that for large energies, compared to the scale set b…
A stringy glimpse into the black hole horizon
Nissan Itzhaki, Lior Liram
We elaborate on the recent claim [arXiv:1702.03583] that non-perturbative effects in , which are at the core of the FZZ duality, render the region just behind the horizon of th…
On the black hole interior in string theoy
Roy Ben-Israel, Amit Giveon, Nissan Itzhaki +1
The potential behind the horizon of an eternal black hole in classical theories is described in terms of data that is available to an external observer -- the reflection coefficien…
On the Stringy Hartle-Hawking State
Roy Ben-Israel, Amit Giveon, Nissan Itzhaki +1
We argue that non-perturbative stringy effects render the Hartle-Hawking state associated with the eternal black hole singular at the horizon. We discuss implicat…
Stringy Horizons and UV/IR Mixing
Roy Ben-Israel, Amit Giveon, Nissan Itzhaki +1
The target-space interpretation of the exact (in ) reflection coefficient for scattering from Euclidean black-hole horizons in classical string theory is studied. For concreten…
