Punctures from Probe M5-Branes and N=1 Superconformal Field Theories

Ibrahima Bah, Maxime Gabella, Nick Halmagyi

We study probe M5-branes in N=1 AdS5 solutions of M-theory that arise from M5-branes wrapped on a Riemann surface. Using the BPS condition from kappa-symmetry, we classify supersym…

Holographic thermalization, quasinormal modes and superradiance in Kerr-AdS

Vitor Cardoso, Oscar J. C. Dias, Gavin S. Hartnett +2

Black holes in anti-de Sitter (AdS) backgrounds play a pivotal role in the gauge/gravity duality where they determine, among other things, the approach to equilibrium of the dual f…

Vortices in holographic superfluids and superconductors as conformal defects

Oscar J. C. Dias, Gary T. Horowitz, Nabil Iqbal +1

We present a detailed study of a single vortex in a holographic symmetry breaking phase. At low energies the system flows to an nontrivial conformal fixed point. Novel vortex physi…

Uplifting the baryonic branch: a test for backreacting anti-D3-branes

Anatoly Dymarsky, Stefano Massai

Placing D3 or anti-D3-branes at the tip of the Klebanov-Strassler background results in uplifting the baryonic branch of the moduli space of the dual field theory. In this paper we…

From correlation functions to event shapes

A. V. Belitsky, S. Hohenegger, G. P. Korchemsky +2

We present a new approach to computing event shape distributions or, more precisely, charge flow correlations in a generic conformal field theory (CFT). These infrared finite obser…
