Dyson equations for correlators of Wilson loops

Diego Correa, Pablo Pisani, Alan Rios Fukelman +1

By considering a Gaussian truncation of super Yang-Mills, we derive a set of Dyson equations that account for the ladder diagram contribution to connected correlators…

Non-Abelian gauged supergravities as double copies

Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1

Scattering amplitudes have the potential to provide new insights to the study of supergravity theories with gauged R-symmetry and Minkowski vacua. Such gaugings break supersymmetry…

Universal relaxation in a holographic metallic density wave phase

Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1

In this work, we uncover a universal relaxation mechanism of pinned density waves, combining Gauge/Gravity duality and effective field theory techniques. Upon breaking translations…

Marginal deformations of WZW models and the classical Yang-Baxter equation

Riccardo Borsato, Linus Wulff

We show how so-called Yang-Baxter (YB) deformations of sigma models, based on an R-matrix solving the classical Yang-Baxter equation (CYBE), give rise to marginal current-current d…

Deformations of the circular Wilson loop and spectral (in)dependence

Michael Cooke, Amit Dekel, Nadav Drukker +2

In this paper we study the expectation value of deformations of the circular Wilson loop in super Yang-Mills theory. The leading order deformation, known as the Bremss…

Holographic Response of Electron Clouds

Ulf Gran, Marcus Tornsö, Tobias Zingg

In order to make progress towards more realistic models of holographic fermion physics, we use gauge/gravity duality to compute the dispersion relations for quasinormal modes and c…
