An Effective Field Theory of Quantum Black Hole Horizons

I develop an effective theory which describes black holes with quantum
mechanical horizons that is valid at scales long compared to the
Schwarzschild radius but short compared to the lifetime of the black
hole. The formalism allows one to calculate the quantum mechanical
effects in scattering processes involving black hole asymptotic states.
The EFT Wightman functions which describe Hawking radiation in the Unruh
vacuum are not Planck suppressed and are actually enhanced relative to

Impact of the Past Lecture Series - Anti Semitism Past and Present

February 5, 2020
Shootings at synagogues in the U.S., attacks on Jewish people in France, and a fierce debate within the British Labour party. Anti-Semitism is back, but why? And what is different from the experiences of the 1930s? Speakers from the U.S. and Europe debate the issue:
