I argue that scattering theory for massless particles in Minkowski space should be reformulated as a mapping between past and future representations of an algebra of densities on the conformal boundary. These densities are best thought of as living on the momentum space light cone dual to null infinity, which describes the simultaneous eigenstates of the BMS generators. The currents describe the flow of other quantum numbers through the holographic screen at infinity. They are operator valued… 

Holographic Space-time, Newton's Law and the Dynamics of Black Holes

We revisit the construction of models of quantum gravity in d dimensional Minkowski space in terms of random tensor models, and correct some mistakes in our previous treatment of the subject. We find

Soft Gravitons and the Flat Space Limit of Anti-deSitter Space

We argue that flat space amplitudes for the process $ 2 \to n$ gravitons at center of mass energies $\sqrt{s}$ much less than the Planck scale, will coincide approximately with amplitudes calculated

Holographic Space-Time and Quantum Information

The formalism of Holographic Space-time (HST) is a translation of the principles of Lorentzian geometry into the language of quantum information. Intervals along time-like trajectories, and their

Residual Local Supersymmetry and the Soft Gravitino.

It is shown that there exists an infinite tower of fermionic symmetries in pure d=4, N=1 supergravity on an asymptotically flat background, and that these charges commute into charges associated with the (unextended) Bondi-Metzner-Sachs group, providing a supersymmetrization of the BMS translations.

Note on Localized Objects as Constrained States of Holographic Variables

We argue that localized excitations in Minkowski space must be thought of as constrained states of holographic degrees of freedom. The Minkowski "vacuum" is in fact a density matrix of infinite

D ec 2 01 5 Brown-HET-1689 Residual Local Supersymmetry and the Soft Gravitino

We show that there exists an infinite tower of fermionic symmetries in pure d = 4, N = 1 supergravity on an asymptotically flat background. The Ward identities associated with these symmetries are

Lectures on the Infrared Structure of Gravity and Gauge Theory

This is a redacted transcript of a course given by the author at Harvard in spring semester 2016. It contains a pedagogical overview of recent developments connecting the subjects of soft theorems,

On the Limits of Effective Quantum Field Theory: Eternal Inflation, Landscapes, and Other Mythical Beasts

We recapitulate multiple arguments that Eternal Inflation, and the String Landscape are actually part of the Swampland: ideas in Effective Quantum Field Theory that do not have a counterpart in

Cosmological Implications of the Bekenstein Bound

A brief review of "Holographic Space-Time" in the light of the seminal contributions of Jacob Bekenstein.



New symmetries of massless QED

A bstractAn infinite number of physically nontrivial symmetries are found for abelian gauge theories with massless charged particles. They are generated by large U(1) gauge transformations that

M theory as a matrix model: A Conjecture

We suggest and motivate a precise equivalence between uncompactified 11-dimensional M theory and the N={infinity} limit of the supersymmetric matrix quantum mechanics describing D0 branes. The

Asymptotic Symmetries of Massless QED in Even Dimensions

We consider the scattering of massless particles coupled to an abelian gauge field in 2n-dimensional Minkowski spacetime. Weinberg's soft photon theorem is recast as Ward identities for infinitely

The world as a hologram

According to ’t Hooft the combination of quantum mechanics and gravity requires the three‐dimensional world to be an image of data that can be stored on a two‐dimensional projection much like a

Higher-Dimensional Supertranslations and Weinberg's Soft Graviton Theorem

Asymptotic symmetries of theories with gravity in d = 2m+2 spacetime dimensions are reconsidered for m > 1 in light of recent results concerning d = 4 BMS symmetries. Weinberg’s soft graviton theorem

Symmetries of asymptotically flat four-dimensional spacetimes at null infinity revisited.

It is shown that the symmetry algebra of asymptotically flat spacetimes at null infinity in 4 dimensions should be taken as the semidirect sum of supertranslations with infinitesimal local conformal

Black hole evaporation without information loss

An approach to black hole quantization is proposed wherein it is assumed that quantum coherence is preserved. After giving our motivations for such a quantization procedure we formulate the

BMS charge algebra

A bstractThe surface charges associated with the symmetries of asymptotically flat four dimensional spacetimes at null infinity are constructed. They realize the symmetry algebra in general only up

Evidence for a New Soft Graviton Theorem

The single-soft-graviton limit of any quantum gravity scattering amplitude is given at leading order by the universal Weinberg pole formula. Gauge invariance of the formula follows from global

A covariant entropy conjecture

We conjecture the following entropy bound to be valid in all space-times admitted by Einstein's equation: let A be the area of any two-dimensional surface. Let L be a hypersurface generated by
