Note on the Pure State of Old Black Holes in Some Models of Asymptotically Flat Quantum Gravity
Abstract
We analyze two old models of black holes to see whether they realize the AdS/CFT paradigm of ``multiple representations of bulk data by boundary states that differ only in the expectation value of exponentially complex operators" . We find that the explanation of the firewall paradox in these models is much simpler and corresponds to the naive way entanglement is resolved when small constituents escape from a complex chaotic quantum system. The real issue is that the quantum field theory (QFT) picture of the states near the boundary of a causal diamond is wrong. The phrase in quotes above is correct in our models because most of the states associated with any causal diamond cannot be associated with ANY states in quantum field theory.
