Quantum character of black holes
Adam D. Helfer
Black holes are extreme manifestations of general relativity, so one might hope that exotic quantum effects would be amplified in their vicinities, perhaps providing clues to quant…
Quantum nature of black holes
Adam D. Helfer
I reconsider Hawking's analysis of the effects of gravitational collapse on quantum fields, taking into account interactions between the fields. The ultra-high energy vacuum fluctu…
Trans-Planckian Modes, Back-Reaction, and the Hawking Process
Adam D. Helfer
Hawking's prediction of black-hole evaporation depends on the application of known physics to fantastically high energies -- well beyond the Planck scale. Here, I show that before…
On Quantum Inequalities
Adam D. Helfer
Building on the "quantum inequalities" introduced by Ford, I argue that the negative local energies encountered in quantum field theory can only be observed by detectors with posit…
