Shape Dependence of Holographic Rényi Entropy in General Dimensions
Lorenzo Bianchi, Shira Chapman, Xi Dong +3
We present a holographic method for computing the response of Rényi entropies in conformal field theories to small shape deformations around a flat (or spherical) entangling surfac…
Green-Schwarz superstring on the lattice
Lorenzo Bianchi, Marco S. Bianchi, Valentina Forini +2
We consider possible discretizations for a gauge-fixed Green-Schwarz action of Type IIB superstring. We use them for measuring the action, from which we extract the cusp anomalous…
Perturbation theory for string sigma models
Lorenzo Bianchi
In this thesis we investigate quantum aspects of the Green-Schwarz superstring in various AdS backgrounds relevant for the AdS/CFT correspondence, providing several examples of per…
Lattice and string worldsheet in AdS/CFT: a numerical study
Valentina Forini, Lorenzo Bianchi, Marco S. Bianchi +2
We consider a possible discretization for the gauge-fixed Green-Schwarz (two-dimensional) sigma-model action for the Type IIB superstring and use it for measuring the cusp anomalou…
