Geometric duality between effective field theories I: scattering amplitudes
Tomas Brauner, Yang Li, Diederik Roest +1
We propose a novel type of duality that connects a sequence of well-known theories with even-multiplicity scalar amplitudes: it relates the Yang-Mills theory coupled to a specific…
Entanglement Entropy in Scalar Quantum Electrodynamics
Samuel Fedida, Anupam Mazumdar, Sougato Bose +1
We find the entanglement entropy of a subregion of the vacuum state in scalar quantum electrodynamics, working perturbatively to the 2-loops level. Doing so leads us to derive the…
Non-linear Electrodynamics from Massive Gravity
Thomas Flöss, Diederik Roest, Tom Westerdijk
As a counterpart to the four-fermion interaction, which describes massive vector exchange at low energies, we investigate the low energy effective action of photons under exchange…
Non-Lorentzian IIB Supergravity from a Polynomial Realization of SL(2,R)
Eric Bergshoeff, Kevin T. Grosvenor, Johannes Lahnsteiner +2
We derive the action and symmetries of the bosonic sector of non-Lorentzian IIB supergravity by taking the non-relativistic string limit. We find that the bosonic field content is…
Non-Lorentzian theories with and without constraints
Eric A. Bergshoeff, Joaquim Gomis, Axel Kleinschmidt
We exhibit a new method of constructing non-Lorentzian models by applying a method we refer to as starting from a so-called seed Lagrangian. This method typically produces addition…
Branched SL(2,Z) Duality
Eric Bergshoeff, Kevin T. Grosvenor, Johannes Lahnsteiner +2
We investigate how SL(2,Z) duality is realized in nonrelativistic type IIB superstring theory, which is a self-contained corner of relativistic string theory. Within this corner, w…
