Bremsstrahlung function from Goldstone bosons in AdS $_{2}$

Federico Castellani, Lorenzo Di Pietro, Valentina Forini +1

We study quantum field theory on the AdS $_{2}$ worldsheet of the fundamental string dual to the half-BPS Wilson line of $N = 4$ 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…
