Black Hole Vacua and Rotation

Understand

Recent developments suggest that the near-region of rotating black holes behaves like a CFT.

• To understand this better, I propose to study quantum fields in this region.
• An instructive approach for this might be to put a large black hole in AdS and to think of the entire geometry as a toy model for the ``near-region".
• Quantum field theory on rotating black holes in AdS can be well-defined (unlike in flat space), if fields are quantized in the co-rotating-with-the-horizon frame.
