On the scattering of gluons in the GKP string
Lorenzo Bianchi, Marco S. Bianchi
We compute the one-loop S-matrix for the light bosonic excitations of the GKP string at strong coupling. These correspond, on the gauge theory side, to gluon insertions in the GKP…
Rényi entropy and conformal defects
Lorenzo Bianchi, Marco Meineri, Robert C. Myers +1
We propose a field theoretic framework for calculating the dependence of Rényi entropies on the shape of the entangling surface in a conformal field theory. Our approach rests on r…
Worldsheet scattering for the GKP string
Lorenzo Bianchi, Marco S. Bianchi
We initiate the perturbative study of the S-matrix for the excitations on top of the GKP vacuum at strong coupling. Using the string sigma model action expanded around the null cus…
Quantum dispersion relations for the GKP string
Lorenzo Bianchi, Marco S. Bianchi
We compute the one-loop correction to the dispersion relations of the excitations of the sigma model dual to ABJM theory, expanded around the cusp background. T…
