Abstract
We give a new proof of Hardy uncertainty principle, up to the endpoint case, which is only based on calculus. The method allows us to extend Hardy uncertainty principle to Schrödinger equations with nonconstant coefficients. We also deduce optimal Gaussian decay bounds for solutions to these Schrödinger equations.
