Multiparticle Factorization and the Rigidity of String Theory
Nima Arkani-Hamed, Clifford Cheung, Carolina Figueiredo +1
Is string theory uniquely determined by self-consistency? Causality and unitarity seemingly permit a multitude of putative deformations, at least at the level of two-to-two scatter…
Holographic Screen Sequestration
Aidan Chatwin-Davies, Pompey Leung, Grant N. Remmen
Holographic screens are codimension-one hypersurfaces that extend the notion of apparent horizons to general (non-black hole) spacetimes and that display interesting thermodynamic…
Holographic entanglement from the UV to the IR
Xi Dong, Grant N. Remmen, Diandian Wang +2
In AdS/CFT, observables on the boundary are invariant under renormalization group (RG) flow in the bulk. In this paper, we study holographic entanglement entropy under bulk RG flow…
Bespoke Dual Resonance
Clifford Cheung, Grant N. Remmen
Dual resonance is one of the great miracles of string theory. At a fundamental level, it implies that the particles exchanged in different channels are subtly equivalent. Furthermo…
Extremal Kerr black holes as amplifiers of new physics
Gary T. Horowitz, Maciej Kolanowski, Grant N. Remmen +1
We show that extremal Kerr black holes are sensitive probes of new physics. Stringy or quantum corrections to general relativity are expected to generate higher-curvature terms in…
Stringy Dynamics from an Amplitudes Bootstrap
Clifford Cheung, Grant N. Remmen
We describe an analytic procedure whereby scattering amplitudes are bootstrapped directly from an input mass spectrum and a handful of physical constraints: crossing symmetry, boun…
Charged Dilatonic Spacetimes in String Theory
Achilleas P. Porfyriadis, Grant N. Remmen
We construct and study general static, spherically symmetric, magnetically charged solutions in Einstein-Maxwell-dilaton gravity in four dimensions. That is, taking Einstein gravit…
