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…
Probing the dynamics of stringy flux tubes with large -charge
Davide Bonomi, Valentina Forini, Valentina Giangreco M. Puletti +2
We study the generalized cusp anomalous dimension, or quark-antiquark potential on the three-sphere, in the presence of a large -charge and at strong coupling. Considering t…
Dispersion relation from Lorentzian inversion in 1d CFT
Davide Bonomi, Valentina Forini
Starting from the Lorentzian inversion formula, we derive a dispersion relation which computes a four-point function in 1d CFTs as an integral over its double discontinuity. The cr…
An update on supersphere non linear sigma model on the lattice
Ilaria Costa, Valentina Forini, Agostino Patella +1
We consider the discretized version of the sigma-model with supersphere target space and present a preliminary numerical study of bosonic and fermioni…
