Bremsstrahlung function from Goldstone bosons in AdS
Federico Castellani, Lorenzo Di Pietro, Valentina Forini +1
We study quantum field theory on the AdS worldsheet of the fundamental string dual to the half-BPS Wilson line of super Yang-Mills. We consider a recently propo…
Symmetry extension by condensation defects II: general dimensions and higher-groups
Matteo Bertolini, Lorenzo Di Pietro, Stefano C. Lanza +1
We discuss a class of symmetry structures in general spacetime dimension that arise when gauging symmetries in theories with a cubic 't Hooft anomaly. The anomaly mixes two Abelian…
Resurgence and Expansion in Integrable Field Theories
Lorenzo Di Pietro, Marcos Mariño, Giacomo Sberveglieri +1
In theories with renormalons the perturbative series is factorially divergent even after restricting to a given order in , making the expansion a natural testing ground…
Renormalization of Galilean Electrodynamics
Shira Chapman, Lorenzo Di Pietro, Kevin T. Grosvenor +1
We study the quantum properties of a Galilean-invariant abelian gauge theory coupled to a Schrödinger scalar in 2+1 dimensions. At the classical level, the theory with minimal coup…
3d Abelian Gauge Theories at the Boundary
Lorenzo Di Pietro, Davide Gaiotto, Edoardo Lauria +1
A four-dimensional Abelian gauge field can be coupled to a 3d CFT with a symmetry living on a boundary. This coupling gives rise to a continuous family of boundary conformal…
