Europe/Berlin
Description
Holography has long been employed to explore the behavior of strongly interacting theories in regimes inaccessible to perturbative techniques, with phase transitions remaining among the most intriguing phenomena. Indeed, while a holographic version of QCD is still elusive, numerous strongly-coupled theories that mimic certain aspects of QCD have been found with a known holographic dual, and they offer controlled examples to explore such nonperturbative dynamics.
After recalling a few relevant concepts regarding the holographic duality, I will introduce and discuss two examples of theoretical frameworks that allow such an analysis of first-order transitions, exploring confinement in a top-down model and finite-density in a bottom-up one, the latter including a real-time simulation. I will present the numerical implementation of these holographic setups, focusing on the obtained results and their interpretation: the showcased instances will illustrate how holography, and in particular numerical methods thereof, can be a useful tool to probe nonperturbative dynamics in strongly coupled systems from first principles.
