This program will explore recent developments in describing the dynamics of strongly-coupled quantum systems using the notion of fundamental, quantum bounds on transport, and their interplay with quantum chaos. Experiments, as well as theoretical results coming from quantum field theory, lattice models and gauge/gravity duality, hint that the late time dynamics of these systems is governed by a Planckian timescale, the shortest allowed by quantum mechanics. This timescale provides a bound on the growth of chaos and the scrambling of quantum information, saturated in theories with Einstein holographic duals. From the point of view of thermoelectric transport, this timescale may bound the diffusive processes which underpin the ubiquitous T-linear resistivity of the bad metallic phase of high Tc superconductors and other unconventional materials. Diffusive transport also emerges in exactly solvable, quantum chaotic models like the Sachdev-Ye-Kitaev model.
By bringing together international leaders in condensed matter and high energy physics, we aim at enhancing our current understanding by combining experimental results and the various theoretical, non-perturbative approaches to these problems. Participants will include experts in thermoelectric transport experiments, hydrodynamics, gauge/gravity duality, numerical and analytic condensed matter theory and conformal field theory.
