$L^2$ restriction bounds for analytic continuations of quantum ergodic Laplace eigenfunctions

Abstract

We prove a quantum ergodic restriction (QER) theorem for real hypersurfaces $\Sigma \subset X,$ where $X$ is the Grauert tube associated with a real-analytic, compact Riemannian manifold. As an application, we obtain $h$ independent upper and lower bounds for the $L^2$ - restrictions of the FBI transform of Laplace eigenfunctions restricted to $\Sigma$ satisfying certain generic geometric conditions.
