Non-Invertible Symmetries and Boundaries for Two-Dimensional Fermions

Guillermo Arias-Tamargo, Philip Boyle Smith, Rishi Mouland +1

We study the relation between boundary conditions and categorical symmetries of two-dimensional fermionic conformal field theories. We determine all anomaly-free invertible global…

An M2/M5 Duality from the Giant Graviton Expansion

Heng-Yu Chen, Nick Dorey, Sanefumi Moriyama +2

We conjecture a precise relation between the superconformal indices of two theories defined in different spacetime dimensions. The first is the three-dimensional ABJM theory descri…

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…

Giant Gravitons and Volume Minimisation

Heng-Yu Chen, Nick Dorey, Sanefumi Moriyama +2

We establish a precise correspondence between the giant graviton expansion of the superconformal index of field theories in , and the master volume formalism of Gauntlett,…

Phases of 2d Gauge Theories and Symmetric Mass Generation

Rishi Mouland, David Tong, Bernardo Zan

We study the dynamics and phase structure of Abelian gauge theories in dimensions. These include gauge theory coupled to a scalar and a fermion, as well as the two-f…

Extremal couplings, graviton exchange, and gluon scattering in AdS

Shai M. Chester, Rishi Mouland, Jesse van Muiden

Extremal cubic couplings in AdS relate bulk fields such that . Such couplings lead to divergent 3-point Witten diagrams, and do not occur in theories with maximal s…
