State independence for tunneling processes through black hole horizons and Hawking radiation
State independence black hole horizons Hawking radiation
2010/12/27
Tunneling processes through black hole horizons have recently been investigated in the framework of WKB theory discovering interesting interplay with the Hawking radiation. In this paper we instead ad...
Accelerated detectors and worldsheet horizons in AdS/CFT
Accelerated detectors worldsheet horizons
2010/12/24
We use the AdS/CFT correspondence to discuss the response of an accelerated observer to the quantum vacuum fluctuations. In particular, we study heavy quarks probing a strongly coupled CFT by analysin...

Existence of horizons in Robinson-Trautman spacetimes of arbitrary dimension
arbitrary dimension Robinson-Trautman spacetimes

We derive the higher dimensional generalization of Penrose-Tod equation describing past horizon in Robinson-Trautman spacetimes with a cosmological constant and pure radiation. Results for D=4 dimensi...
