Covariant Phase Space with Boundaries

The Hamiltonian formulation of mechanics has many advantages, but its standard presentation destroys manifest covariance. This can be avoided by using the "covariant phase formalism" of Iyer and Wald, but until recently this formalism has suffered from several ambiguities related to boundary terms and total derivatives. In this talk I will present a new version of the formalism which incorporates boundary effects from the beginning.

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

Please Note: This workshop is not open to the general public, but only to active researchers.

This workshop will focus on quantum aspects of black holes, focusing on applying ideas from quantum information theory.

This meeting is sponsored by the "It from Qubit"collaboration and is followed by the collaboration meeting in New York City.
