超振荡函数是频带受限的函数,其振荡速度可以快于其最快的傅立叶分量。这些函数出现在科学和技术的各个领域,特别是在Y.Aharonov及其合作者引入的弱值的背景下,它们是在量子力学中发现的。超振荡函数作为薛定谔方程的初始条件的演化问题是当今研究的热点,薛定谔方程解的超移位性质编码了超振荡现象在演化过程中的持久性。本文证明了自旋粒子在磁场中的超振荡初始数据的演化具有超移位性质。我们的技巧是基于自旋粒子的精确传播子、与之相关的无穷阶微分算子及其在具有增长条件的整函数的适当空间上的连续性。参考文献
Superoscillating functions are band-limited functions that can oscillate faster than their fastest Fourier component. These functions appear in various fields of science and technology, in particular they were discovered in quantum mechanics in the context of weak values introduced by Y. Aharonov and collaborators. The evolution problem of superoscillatory functions as initial conditions for the Schrödinger equation is intensively studied nowadays and the supershift property of the solution of Schrödinger equation encodes the persistence of superoscillatory phenomenon during the evolution. In this paper, we prove that the evolution of a superoscillatory initial datum for spinning particles in a magnetic field has the supershift property. Our techniques are based on the exact propagator of spinning particles, the associated infinite order differential operators and their continuity on suitable spaces of entire functions with growth conditions.
