Exponential Decay outside of the Light Cone for the Pseudo-Relativistic Non-Autonomous Schrödinger Equation

This article likely presents a mathematical analysis of the Schrödinger equation, a fundamental equation in quantum mechanics. The focus is on a pseudo-relativistic version, which incorporates aspects of special relativity, and a non-autonomous version, meaning the equation's parameters change over time. The key finding seems to be the exponential decay of solutions outside the light cone, a region of spacetime where information cannot travel according to relativity. This suggests the model exhibits behavior consistent with relativistic principles.
