Drifting Oscillations in Axion Monodromy

Raphael Flauger, Liam McAllister, Eva Silverstein +1

We study the pattern of oscillations in the primordial power spectrum in axion monodromy inflation, accounting for drifts in the oscillation period that can be important for compar…

Towards a Holographic Bose-Hubbard Model

Mitsutoshi Fujita, Sarah Harrison, Andreas Karch +2

We present a holographic construction of the large-N Bose-Hubbard model. The model is based on Maxwell fields coupled to charged scalar fields on the AdS2 hard wall. We realize the…

Bootstrapping an NMHV amplitude through three loops

Lance J. Dixon, Matt von Hippel

We extend the hexagon function bootstrap to the next-to-maximally-helicity-violating (NMHV) configuration for six-point scattering in planar super-Yang-Mills theory at…

Mock Modular Mathieu Moonshine Modules

Miranda C. N. Cheng, Xi Dong, John F. R. Duncan +3

We construct super vertex operator algebras which lead to modules for moonshine relations connecting the four smaller sporadic simple Mathieu groups with distinguished mock modular…

Holographic Reconstruction of General Bulk Surfaces

Bartlomiej Czech, Xi Dong, James Sully

We propose a reconstruction of general bulk surfaces in any dimension in terms of the differential entropy in the boundary field theory. In particular, we extend the proof of Headr…

Umbral Moonshine and K3 Surfaces

Miranda C. N. Cheng, Sarah Harrison

Recently, 23 cases of umbral moonshine, relating mock modular forms and finite groups, have been discovered in the context of the 23 even unimodular Niemeier lattices. One of the 2…

The Powers of Monodromy

Liam McAllister, Eva Silverstein, Alexander Westphal +1

Flux couplings to string theory axions yield super-Planckian field ranges along which the axion potential energy grows. At the same time, other aspects of the physics remain essent…

Ghosts in the self-accelerating DGP branch with Gauss-Bonnet effect

Yen-Wei Liu, Keisuke Izumi, Mariam Bouhmadi-Lopez +1

The Dvali-Gabadadze-Porrati brane-world model provides a possible approach to address the late-time cosmic acceleration. However, it has subsequently been pointed out that a ghost…

Light-Front Holographic QCD and Color Confinement

Stanley J. Brodsky, Guy F. de Téramond, Hans Günter Dosch

One of the most fundamental problems in Quantum Chromodynamics is to understand the origin of the mass scale which controls the range of color confinement and the hadronic spectrum…

Universality of Long-Distance AdS Physics from the CFT Bootstrap

A. Liam Fitzpatrick, Jared Kaplan, Matthew T. Walters

We begin by explicating a recent proof of the cluster decomposition principle in AdS_{d+1} from the CFT_d bootstrap in d > 2. The CFT argument also computes the leading interaction…

Cold Black Holes in the Harlow-Hayden Approach to Firewalls

Yen Chin Ong, Brett McInnes, Pisin Chen

Firewalls are controversial principally because they seem to imply departures from general relativistic expectations in regions of spacetime where the curvature need not be particu…

The four-loop remainder function and multi-Regge behavior at NNLLA in planar N=4 super-Yang-Mills theory

Lance J. Dixon, James M. Drummond, Claude Duhr +1

We present the four-loop remainder function for six-gluon scattering with maximal helicity violation in planar N=4 super-Yang-Mills theory, as an analytic function of three dual-co…

Emergent Fermi surfaces, fractionalization and duality in supersymmetric QED

Anson Hook, Shamit Kachru, Gonzalo Torroba +1

We study the physics of 3d supersymmetric abelian gauge theories (with small supersymmetry breaking perturbations) at finite density. Using mirror symmetry, which provides a natura…
