Highly non-equilibrium holography

Project Details


Conventional techniques generally fail to describe how strongly coupled systems evolve after being excited very far from equilibrium. This severely limits our theoretical understanding of time-evolution after a quantum quench, of the creation of the quark gluon plasma in heavy ion collisions, and of pump-probe experiments designed to uncover the mechanism behind high temperature superconductivity.

Holography, also known as gauge/gravity duality, has proven to be a powerful tool to study strongly coupled systems near equilibrium. Transport coefficients that used to be impossible to compute can now be easily obtained from black hole physics. Also, new terms were discovered in the textbook equations of nonlinear hydrodynamics by realizing that these equations must coincide with those governing slowly varying black hole horizons. In recent years, initial steps have been taken to extend holography to highly non-equilibrium regimes, which involves studying gravitational collapse.

This project aims to develop highly non-equilibrium holography into a well-established, powerful tool that can be applied to a variety of physical systems. We will study turbulence in gravitational collapse, perform precision tests of highly non-equilibrium holography, and develop new applications and a deeper understanding of holographic thermalization. Along the way, connections will be made with mathematical physics concepts including integrability and weak turbulence.
