'One of the most surprising predictions of string theory is the AdS/CFT correspondence, which states that string theory in a certain spacetime is dual and equivalent to a quantum field theory. The power of this correspondence lies in the fact that it is a strong-weak duality, relating strongly coupled field theory and weakly coupled string theory, and vice versa. This correspondence is well understood at the level of macrophysics, i.e., thermodynamics and hydrodynamics. One example is the case where the field theory is (a cousin of) QCD; the macrophysics of quark-gluon plasma has been successfully analyzed using the string theory dual.

However, macrophysics is merely an effective, coarse-grained description of the underlying microphysics. The goal of the proposed research is to advance the understanding of AdS/CFT to non-equilibrium microscopic aspects, making use of phenomena linking macro- and microphysics. Such research will provide a foundation on which the known macrophysics of strongly coupled systems can be based, and further allows us to explore quantum physics of gravity. Strongly coupled systems are ubiquitous in nature and quantum gravity effects are important e.g. for the early universe. Therefore, studies of microphysics via AdS/CFT are of major significance.

One phenomenon linking macro- and microphysics is Brownian motion. On the field theory side, a quark immersed in plasma undergoes Brownian motion. One goal is, by studying the string dual of this Brownian particle, to reveal the microphysics of the plasma constituents. Conversely, we can learn about quantum gravity using Brownian motion in field theory. Another link is the Boltzmann equation describing the time evolution of one-particle distribution. On the field theory side this provides a way to study non-equilibrium processes in strongly coupled plasma, while on the gravity side it allows us to study black hole formation systematically.'
