  "abstract": "We establish improved local smoothing estimates for the Schrödinger equation on waveguides. Our results extend the previously known range of exponents in every dimension and are sharp in certain cases. The proof develops a transference argument that preserves the discrete periodic frequency structure, together with a refined decoupling estimate adapted to waveguides. We also derive consequences for Euclidean local smoothing and almost everywhere convergence.",
