Branches of the Black Hole Wave Function Need Not Contain Firewalls
Ning Bao, Sean M. Carroll, Aidan Chatwin-Davies +2
We discuss the branching structure of the quantum-gravitational wave function that describes the evaporation of a black hole. A global wave function which initially describes a cla…
The Boundary of the Future
Chris Akers, Raphael Bousso, Illan F. Halpern +1
We prove that the boundary of the future of a surface consists precisely of the points that lie on a null geodesic orthogonal to such that between and there are…
Pions as Gluons in Higher Dimensions
Clifford Cheung, Grant N. Remmen, Chia-Hsien Shen +1
We derive the nonlinear sigma model as a peculiar dimensional reduction of Yang-Mills theory. In this framework, pions are reformulated as higher-dimensional gluons arranged in a k…
Hidden Simplicity of the Gravity Action
Clifford Cheung, Grant N. Remmen
We derive new representations of the Einstein-Hilbert action in which graviton perturbation theory is immensely simplified. To accomplish this, we recast the Einstein-Hilbert actio…
A Nonlocal Approach to the Cosmological Constant Problem
Sean M. Carroll, Grant N. Remmen
We construct a model in which the cosmological constant is canceled from the gravitational equations of motion. Our model relies on two key ingredients: a nonlocal constraint on th…
Bulk Connectedness and Boundary Entanglement
Ning Bao, Grant N. Remmen
We prove, for any state in a conformal field theory defined on a set of boundary manifolds with corresponding classical holographic bulk geometry, that for any bipartition of the b…
Twofold Symmetries of the Pure Gravity Action
Clifford Cheung, Grant N. Remmen
We recast the action of pure gravity into a form that is invariant under a twofold Lorentz symmetry. To derive this representation, we construct a general parameterization of all t…
