论文摘要
Van Dijk，Nogami和Toyama开发的方法用于获得衰减量子系统的时间进化波函数，被推广到非紧凑型支持的电势和初始波功能。提取并采用了长时间的渐近行为来预测非指数衰减开始的时间尺度。该方法用高斯初始波函数通过ECKART在半线上的潜在障碍物泄漏。
The method developed by Van Dijk, Nogami and Toyama for obtaining the time-evolved wave function of a decaying quantum system is generalized to potentials and initial wave functions of non-compact support. The long time asymptotic behavior is extracted and employed to predict the timescale for the onset of non-exponential decay. The method is illustrated with a Gaussian initial wave function leaking through Eckart's potential barrier on the halfline.
