Let (M, g) be a compact, smooth Riemannian manifold and uh be a sequence of L 2-normalized Laplace eigenfunctions that has a localized defect measure μ in the sense that M\supp (π∗ μ)≠∅ where π: T∗ M→ M is the canonical projection. Using Carleman estimates we prove that for any real smooth closed hypersurface H⊂(M\supp (π∗ μ)) sufficienly close to supp π∗ μ and for all δ> 0,∫ H| uh| 2 d σ H≥ C δ e-φ (τ H)+ δ/h, as h→ 0+. Here, φ (τ)= τ+ O (τ 2) and τ H:= d (H, supp (π∗ μ)). We also show that an analogous result holds for eigenfunctions of Schrödinger operators and give applications to eigenfunctions on warped products and joint eigenfunctions of quantum completely integrable (QCI) systems.
