Symmetry Enhancement, SPT Absorption, and Duality in QED
Shai M. Chester, Zohar Komargodski
Quantum Electrodynamics in 2+1 dimensions (QED) with two Dirac fermions displays time reversal symmetry, nontrivial SPT phases and anomalies. The fate of this theory in its str…
The type IIA Virasoro-Shapiro amplitude in AdS CP from ABJM theory
Shai M. Chester, Tobias Hansen, De-liang Zhong
We consider tree level scattering of gravitons in type IIA string theory on to all orders in , which is dual to the stress tensor correlator in $U(…
The AdS Veneziano amplitude at small curvature
Luis F. Alday, Shai M. Chester, Tobias Hansen +1
We compute the AdS Veneziano amplitude for type IIB gluon scattering in to all orders in in a small curvature expansion. This is achieved by combining a di…
Integral constraints for super-Yang-Mills from a squashed sphere
Shai M. Chester, Ross Dempsey, Debaditya Pramanik +1
Supersymmetric localization and Ward identities have been used in the past several years to derive two integral constraints on the four-point function of the stress-tensor multiple…
Extremal couplings and gluon scattering in M-theory
Shai M. Chester, Rishi Mouland, Jesse van Muiden +1
We consider M-theory on the backgrounds AdS and AdS, which have fixed point locii AdS for . These…
Bootstrapping M-theory Orbifolds
Shai M. Chester, Silviu S. Pufu, Yifan Wang +1
We analyze correlation functions of flavor currents in a family of three-dimensional superconformal field theories, combining analytic bootstrap…
