摘要
We propose that the vacuum state of a scalar field around a black hole is a modified Unruh vacuum. In (1 + 1) dimensions, we show that a free-faller close to such an horizon can be modeled as an inertial observer in a modified Minkowski vacuum. The modification allows for information-leaking correlations at high frequencies. Using a Gaussian detector centered at k(0), we find that the expectation value of the number operator for a detector crossing the horizon is proportional to 1/vertical bar k(0)vertical bar , implying that the free-faller will observe unbounded numbers of high-energy photons, i.e. a firewall.
