To address this question, we investigate the long-time behavior of optimal mixing in an advection--diffusion equation using a shell model framework, a reduced model that captures the essential kinematics of advection and diffusion. Our focus is on quantifying the decay of scalar variance, measured by the shell-model analogue of the $H^{-1}$ mix-norm, under enstrophy-constrained stirring. We perform long-time computations using both local-in-time (maximizing the instantaneous mixing rate) and global-in-time (maximizing mixedness at a prescribed final time) optimization strategies. For mixing with diffusion ($\\kappa>0$), the numerical results for both strategies show that the scalar length scale is eventually limited by a generalized Batchelor scale, in close agreement with theoretical predictions. In this regime, the shell-model analogue of the $H^{-1}$ mix-norm decays exponentially in time at a rate independent of the diffusivity $\\kappa$. Compared with the purely advective case ($\\kappa=0$), diffusion significantly enhances the long-time mixing rate; moreover, increasing diffusivity further improves mixing efficiency by reducing the prefactor. Guided by these numerical observations, we derive new conditional lower bounds on the decay rate of the $H^{-1}$ norm that are strictly independent of the diffusivity parameter $\\kappa$ when $\\kappa>0$. The computed decay rates are consistent with our theoretical bounds.\n\nThis is joint work with Baole Wen, Christian Seis, and Charles R.

Working in the geodesic approximation, we find analytic continuations that probe the interior of rotating and charged black holes.

We implement these continuations on the momentum space two-point function and exemplify this in several black hole backgrounds. We also identify position space analytic continuations achieving the same task that incorporate different continued momentum space correlators. These correspond to non-perturbative corrections to the WKB approximation. We demonstrate this explicitly in the rotating BTZ black hole by showing that the interior geodesics contribute to the continued position space correlator and motivate a picture for how these contributions arise in higher dimensions. For AdS Schwarzschild, we identify the analytically continued solution that captures the bouncing geodesic.
