      Probing confinement observables with numerical holography in quiver field theories
      Abstract:
      Holography has long been employed to explore the behavior of strongly interacting theories in regimes inaccessible to perturbative techniques, with confinement remaining one of the most intriguing phenomena. Indeed, while a holographic version of QCD still remains elusive, numerous theories that mimic certain aspects of QCD have been found with a known holographic dual: among them, the family of quiver field theories considered here. After recalling a few relevant concepts, I will introduce and discuss the theoretical framework and numerical implementation of two holographic observables in these theories: the Wilson loop and entanglement entropy, which have been shown, at least in some examples, to be linked to confinement. I will then present the numerical results and their interpretation, showing the emergence of distinct regimes corresponding to conformal, confining, and screened behaviors, and suggesting the presence of partial deconfinement.
