| 11:00 - 12:00 Journal Club: Experiment & Phenomenology – meeting Bounds on Transport from Univalence and Pole-skipping School PARTICLES AND ACCELERATORS Abstract: Finding the bounds of the transport coefficient has captivated physicists concerned with time-dependent collective dynamics. There have been proposed numerous bounds such as Sachdev’s relaxation time bound, lower bounds on diffusion and viscosity, upper bounds on diffusion, and a bound on the speed of sound. These bounds usually rely on physical principles such as the uncertainty principle and causality. In this paper a new set of methods and sufficient conditions, combining analytic properties of hydrodynamics and the theory of univalent (complex holomorphic and injective) functions, for deriving exact, and sharp bou ... |
