On the phases of gravity and the black hole information paradox

26.09.2016 16:00 – 18:00

The conflict between quantum mechanics and gravity is perhaps most sharply manifested in the physics of black holes, where it gives rise to the so-called black hole information paradox. These objects appear to destroy the information
contained in them, despite the fact that this process is forbidden by one of the fundamental tenets of quantum mechanics. In this colloquium some of the possible phases of gravity will be described. Relations between the long time behavior of correlation functions in quantum field theory and the black hole information paradox will be described.

Limitations on the role that (semi-) classical geometry can play in describing certain features of quantum gravity will emerge from this discussion.
